How to Accurately Gauge Airflow at an Air Vent

A comfortable and healthy atmosphere must always be maintained indoors, which means that sufficient airflow is crucial. Air vents and flow bar diffusers are essential for controlling airflow in HVAC systems. For HVAC performance optimization and spotting potential problems influencing interior air quality, it’s essential to precisely measure the airflow at air vents. In this blog, we’ll look at practical techniques for measuring airflow at air vents and explain why hiring Tecnalco, a reputable HVAC manufacturer in the UAE, is the ideal option for high-quality flow bar diffusers.

How to accurately gauge airflow at an air vent

  1. Use an Anemometer

Anemometer is a portable instrument that is used to gauge airflow. Place the anemometer next to the air vent and use it to gauge the air’s velocity as it enters or leaves the vent. Make sure the vent is clear and the airflow is constant when taking the readings to get reliable results. Airflow rates can be quickly and accurately estimated with an anemometer.

  1. Use a flow hood


Specialized equipment known as flow hoods are used to measure airflow at air vents. These gadgets are made up of a capture hood and a digital flow meter. When using a flow hood, place the cover over the vent so that the flow meter can accurately measure the amount of air flowing through the vent. HVAC experts often use flow hoods for thorough airflow analysis.

  1. Use a Pitot tube

Another tool used to measure airflow velocity is a Pitot tube. The idea behind this equipment is that the speed and pressure of moving air are inversely related. You can gauge the pressure differential between the tube’s open end and the side holes by putting the Pitot tube into the airflow stream at the vent. This measurement assists in precisely calculating the airflow’s velocity.


Maintaining a cozy and healthy home atmosphere depends on accurately measuring airflow through air vents. You can measure the airflow velocity precisely by utilizing anemometers, flow hoods, or Pitot tubes.

Typical HVAC System Types and Operations

The purpose of an HVAC system, short for Heating Ventilation and Air Conditioning, is to make the indoor air clean and comfortable. The HVAC systems bought from the HVAC manufacturers in UAE provide heating, cooling, ventilation and temperature control for the room they are placed in.

There are mainly two types of HVAC systems – the ducted kind and the ductless kind.

In the ductless variety, the air is pushed through a series of air ducts as part of cooling and heating. In the ductless system, there will be no air ducts, and the main unit pushes air through other methods.

The Split system AC

The Split system is the most commonly used HVAC system in residential systems, since it contains separate components for heating and cooling. There will be a thermostat to control the temperature. This is the ducted kind and can be bought from Technalco, the best HVAC manufacturers in UAE .

Zoned System

The zoned system provides a more comfortable environment for users as it gives them greater control over the temperature. It is mostly used in large homes with multiple HVAC systems.

Packaged heating and cooling systems

This is mainly used in buildings with very less storage space. Hence their heating and cooling components like the compressor, condenser and evaporator are stored within a single unit, and stored somewhere else, mainly roof, attic, etc. They cost less than split systems, can be easily installed and maintained just as easily.

Hybrid Split system

The hybrid split system has so many similarities with the split systems. However, the difference is that the air conditioning system does not rely solely on gas for the heating, but can switch to electric power when needed.

The ductless variety – portable spot cooler and heat pump

If you are going for the ductless HVAC systems, then you will find them so commonly available from the HVAC manufacturers in UAE. The portable spot cooler and the portable heat pump are the two most common varieties of the ductless system. And then you have the Hydronic heating system, where the heating system uses liquid to heat the room and not air.

The portable spot coolers are like portable AC units and used mainly in large rooms, outdoor space and manufacturing facilities. They draw in the ambient air, push it through the closed loop coil, cools it with the refrigerant and then pumps it back into space.

The portable heat pump also works in a similar fashion to the spot cooler, the only difference is that it has a heating option meant for colder environments. So you can switch it to the heat mode whenever needed and instead of cool air, the system dispenses warm air.

You can remember that:

  • The hybrid systems are the most preferred system because they are energy saving.
  • The split systems are most commonly used HVAC systems.
  • The packaged systems are just perfect for small houses.

The HVAC systems will function optimally when their maintenance is done regularly. Replacement of the air filters will ensure their functioning to the fullest capacity. You can buy the filters from a reputed and reliable air filter supplier in UAE to ensure the systems work the longest to their maximum potential. Get in touch with犀利士

Advantages of Timely Replacing Your Air Purifier Filter

Over the years the quality of indoor air has been compromised a lot. This has resulted in the popularity of indoor air purifiers. Indoor air purifiers put up a lot of effort to filter out allergens and pollutants to give us better-quality air to breathe. It’s crucial to remember that air purifier filters need routine upkeep, including prompt replacements. We at Tecnalco can help if you’re looking for an air filter supplier in the UAE. Read on to learn more about the advantages of changing your air purifier filter.

Why should you replace air purifier filters?

Air purifiers require filters that are essential to get rid of airborne pollutants including dust, pollen, pet hair, mold spores, and even dangerous particles like germs and viruses. These filters lose their efficiency over time as they fill up with contaminants and get obstructed. The best indoor air quality may be maintained by routinely replacing the filters, which guarantees the air purifier will keep working effectively.

How do you know it’s time for an air filter replacement?

Most air purifiers have indications that let you know when it’s time to change the filter. These indications are influenced by a variety of variables, such as the number of pollutants present, the duration of usage, etc. Other indicators that the filter needs to be changed are a reduction in airflow, an increase in air purifier noise, or a lingering nauseating odor.

How frequently does your air purifier need an air filter replacement?

There are various factors that call for the need to replace air filters such as manufacturer recommendations, the type of air purifier you have and the number of pollutants lurking in your home or office. In general, it is advised to change the filters every 6 to 12 months, but for specific instructions, it is necessary to refer to the user’s manual or contact the manufacturer or a reputable air filter supplier.

Benefits of regularly replacing your air purifier filter

Here are some of the benefits of replacing your air filter:

  • Improved Indoor Air Quality – When you replace your air filter regularly, it ensures that your air purifier effectively captures and removes pollutants, leading to cleaner and healthier indoor air. This is very much important in the UAE, where dust and sand particles are common due to the desert environment.
  • Enhanced Respiratory Health – A properly functioning air purifier will remove any allergens and irritants from the air thus eliminating any breathing issues such as allergies, asthma, and respiratory infections. This is particularly beneficial for people with sensitivities to airborne pollutants.
  • Extended Lifespan of the Air Purifier – When you replace your filter regularly, it will prevent excessive strain on the air purifier’s motor and components. This will extend its lifespan and reduce the need for costly repairs or replacements.
  • Energy Efficiency – A clogged or dirty filter can prevent proper airflow in an air purifier. This causes the purifier to work harder and consume more energy. By replacing the filter in a timely manner, you can maintain the energy efficiency of your air purifier, leading to potential cost savings in the long run.

To sum it up,

It is necessary to replace your air purifier filter regularly to maintain optimal indoor air quality, promote respiratory health, and extend the lifespan of your air purifier.

Access Control Security: A Necessity for your Business

With an access control system, you can limit, control and manipulate the access of information and information processing systems and protect sensitive information in your business and office. Every business must have partnership with access panel suppliers in UAE and install the right kind of access control system to minimise any kind of threat that could affect their business’s smooth functioning.

Keeping that in mind, what is an access control system?

Access control system and its benefits

With an access control system, you can control who enters your business, and this would render more protection to your employees and business. It gives better control of where and when people can enter or exit. You can have a detailed discussion on the access door suppliers in UAE to know what kind of system you need to include for your business.

Check out the multiple benefits of installing the perfect access control system in your enterprise:

Control, monitoring and reporting

Apart from controlling and monitoring who comes in and goes out at any given point of time, you can always have an audit of all the people that come and go. This way when an incident occurs, all you need to do is review the reports and reach a conclusion and hand them over to the authorities if needed.

Much better option than the traditional key system

Most businesses have completely stopped using the traditional keys system in their premises to ensure additional security. This way, it wouldn’t be a problem anymore when an employee loses the key because the system administrators can remotely lock usage and deal them another access card or ID badge with the chip. Check out the different options available with the access panel suppliers in UAE to know what kind of a system you need.

A good way to contain internal security threats

With the access control system in place, you can not only control the incidence of outside threat, you can also control the instances of internal theft, especially when you have a lot of sensitive and valuable confidential information within the premises.

Areas where access control systems are necessary

It is imperative to identify areas that are in dire need of access control systems because then you can devote more time and effort to secure them.

Consider the strong areas of your business, and secure them:

Main entrance, including reception – Access control must be incorporated in areas where people come in and go all the time. An automated access control system can keep track of employees and visitors.

Turnstiles – The main entrance areas and often, other floors may have turnstiles, to enforce one-way human traffic. This allows only one person to travel at a single time.

Elevators – Obviously, one of the most important areas of business, so there should be sufficient monitoring there as well.


Server rooms – The access control system can be manipulated to allow only entrance of authorised personnel.

Manage crowds – When you have certain areas in your building where you need to manage the crowds, like for example elevators, stairways, lobbies, passages, then the access control system is a must.

Vulnerable areas and areas with high security risk – Vulnerable areas are areas where confidential discussion and high level meetings are held.

Parking areas – Obviously, this is another area where you need to restrict access, to control the number of people entering the parking areas.

The access panel suppliers in UAE can help you plan a full-fledged access control system and ensure the security and safety of your offices.

The Functioning of HVAC Systems in Heat Pump

Heat pumps are HVAC systems used to both heat and cool a space. The heat pump works by circulating refrigerant liquid through a system of coils and heating or cooling the air as it passes through. During the summer months, the heat pump operates in cooling mode, absorbing heat from inside the building and releasing it outdoors. During the winter months, the heat pump operates in heating mode, absorbing heat from the outside air and releasing it indoors. The system also typically includes a fan to circulate the air throughout the space. There are many HVAC manufacturers in UAE who can help you with proper air distribution.

What is a heat pump?

A heat pump is a device that transfers heat energy from a cold space to a warmer one by using electricity or another source of power1. It can be used for heating or cooling a home or a building. There are different types of heat pumps, such as air-source, ground-source, water-source, exhaust air, solar-assisted and absorption heat pumps. They have different advantages and disadvantages depending on the climate, the installation cost and the efficiency. A heat pump works by moving a refrigerant (a substance that can change its state from liquid to gas and vice versa) through four main components: a compressor, a condenser, an expansion valve and an evaporator. The refrigerant absorbs heat from the cold space (such as the outdoor air or the ground) in the evaporator and changes into a gas. Then it is compressed by the compressor and releases heat to the warm space (such as the indoor air or water) in the condenser and changes back into a liquid. The expansion valve reduces the pressure of the refrigerant and allows it to enter the evaporator again, completing the cycle.

Heat Pump is a HVAC (Heating, Ventilation, and Air Conditioning) equipment for heating and cooling. It provides thermal control and air conditioning within a building or structure. It can consist of various components, including an air handler, condenser, compressor, evaporator, and furnace. HVAC equipment works by circulating air through a network of ducts, allowing temperature and humidity levels to be controlled.

How does a heat pump work?

A heat pump works by transferring heat from a low-temperature source to a high-temperature sink using a refrigerant that changes its state from liquid to gas and vice versa. A heat pump has four main components: a compressor, a condenser, an expansion valve and an evaporator. Depending on the type of heat pump, the source of heat can be the air, the ground, the water or the exhaust air24. The basic operation of a heat pump is as follows:

  • In heating mode, the refrigerant flows through the evaporator coil in the outdoor unit and absorbs heat from the low-temperature source. The refrigerant evaporates into a gas and is compressed by the compressor, increasing its temperature and pressure. The refrigerant then flows through the condenser coil in the indoor unit and releases heat to the high-temperature sink. The refrigerant condenses into a liquid and passes through the expansion valve, reducing its pressure and temperature. The cycle repeats until the desired indoor temperature is reached.
  • In cooling mode, the refrigerant flows in the opposite direction. The refrigerant flows through the evaporator coil in the indoor unit and absorbs heat from the high-temperature sink. The refrigerant evaporates into a gas and is compressed by the compressor, increasing its temperature and pressure. The refrigerant then flows through the condenser coil in the outdoor unit and releases heat to the low-temperature source. The refrigerant condenses into a liquid and passes through the expansion valve, reducing its pressure and temperature. The cycle repeats until the desired indoor temperature is reached.

A heat pump can provide both heating and cooling by reversing the direction of the refrigerant flow. Some heat pumps also have an electric heater to supplement the heating capacity when the outside temperature is very low.

Different types of heat pumps

As a result of its ability to draw heat from the air, the heat pumps we’re discussing here are referred to as AIR SOURCE HEAT PUMPS. There are also geothermal or water source heat pumps that rely on subterranean heat sources and water pipes. They can be incredibly effective and a sensible option. There are numerous types of heat pump systems available for air source heat pumps.

1. Split system heat pump

Similar to a conventional household central air unit, a split system heat pump consists of two components: an inside unit and an outside unit.

The main distinction is that a split system heat pump contains coils in both the indoor and outdoor units that both absorb and release heat.

This means that a split system heat pump can extract heat from the interior or the exterior, unlike with a split system air conditioner. It can either provide heat to warm up the space or remove heat to chill it.

2. Packaged heat pump

Also known as rooftop unit, a packaged heat pumps work the same way. However, all the coils are housed in a single “packed” device that frequently rests on the building’s roof. Hence, it is also known as a rooftop unit.

Using ductwork that travels through the walls and/or ceiling of the building, heated or cooled air is distributed inside the structure.

Are you unsure of the benefits of a heat pump split system over a packaged unit? Your space will determine the response. A bundled unit can be less costly to set up and up if you have quick access to the roof. They are less effective in structures with more than 10 stories, though.

3. Ducted or ductless heat pumps

The majority of heat pumps use ductwork to distribute heated or cooled air. Yet, there are situations when it is not possible to use ducts, particularly when remodeling an older structure. Or, you might install heating and cooling to an extra room, such as a garage or recent addition.

A ductless mini split heat pump can be a perfect solution in that situation. These systems utilise fan/coil units that are mounted to the wall or ceiling to transmit heat instead of using ducts and refrigerant lines. The drawback of these systems is the requirement for a fan/coil unit in each room that requires climate control. Moreover, they do not properly reduce humidity like a ducted system does.

4. Variable refrigerant flow (VRF) heat pumps

When compared to conventional heating and cooling systems, VRF is a more recent type of heat pump that comes with some incredible advantages. VRF systems can accurately adjust the comfort levels in several zones with various heating and/or cooling requirements while also being more energy-efficient and quieter. In fact, they are able to simultaneously cool and heat various locations.

Advantages of heat pump

  1. Cost-Effective: Heat pumps are one of the most cost-effective methods of heating a home. They can be up to four times more efficient than traditional heating methods, like electric or gas furnaces.
  2. Flexible: Heat pumps can be used in any climate, and they can be used to both heat and cool your home. They can also be used to heat swimming pools and hot tubs.
  3. Environmentally Friendly: Heat pumps are an environmentally friendly choice. They use renewable energy sources, like the sun, to heat your home. This reduces your carbon footprint and helps reduce global warming.
  4. Safe: Heat pumps are a safe and reliable choice for heating your home. They are powered by electricity, so there is no risk of carbon monoxide poisoning or fire hazard.
  5. Quiet: Air source heat pumps are very quiet. They can be used in any room of the home without disrupting your daily activities.

Disadvantages of heat pumps

  1. High Initial Cost – Heat pumps can be expensive to install, and the most efficient models tend to be the costliest.
  2. Not Ideal in Extreme Climates – Heat pumps are not designed to work effectively in very cold climates.
  3. Limited Heating Capacity – Heat pumps may not be able to provide sufficient heat for very large spaces or those with very high ceilings.
  4. Maintenance Requirements – Heat pumps require regular maintenance to ensure they are working efficiently.
  5. High Utility Bills – Heat pumps require more electricity than other heating systems, which may make utility bills higher.

With more recent heat pump technology, it may still be able to reduce HVAC operating expenses, depending on where you live and your individual heating and cooling requirements. An experienced HVAC manufacturer can assist you in weighing your alternatives and selecting the best option.

Breathing Fresh Air: The Importance of Intake and Exhaust Air Louvre Systems

Your structure is built to support a range of enhancements that improve its functionality. Some of these, like the gutters and downspouts, aid in water drainage to stop moisture buildup in a building’s structure and foundation.

The air quality and comfort for everyone inside the building are improved by other elements like vents and windows and intake and exhaust air louvre, which assist the flow of air throughout the building.

What are Architectural Louvers?

they let airflow while preventing rain and other debris from entering the building. Certain architectural concepts enable a building’s façade to supply natural ventilation so that the structure can “breathe.”

Most buildings have louvre systems from the air distribution products manufacturer UAE installed to ensure a smoother air intake and exhaust as well as stronger protection against rain and noise intrusion. Yet, engineers and architects can employ louvres in a variety of ways. They can also be utilised as an inexpensive yet attractive architectural feature for building facades, or as a simple yet effective screening solution for structures to conceal unattractive equipment.

Intake and exhaust air louvres c犀利士
an be used for a variety of performance kinds, such as drainable, non-drainable, resistant to wind-driven rain, combination, thin-line, rated for acoustics, adjustable, and even resistant to extreme weather.

Benefits of Louvers:

  • Energy-Efficiency

Louvre windows contribute to energy efficiency in the home and are more than just decorative window accents. In bathrooms and laundry rooms, louvre windows are a fantastic replacement for exhaust fans because they let humid air escape and prevent moisture buildup.

Louvre windows can also be used for cooling and ventilation in a variety of rooms throughout the house, reducing the need for fans and air conditioning. As a result, your power cost will increase much more gradually.

  • Airflow

Louvre windows are most frequently utilised because of how well they ventilate. Louvre windows enable steady air flow into the home through effective ventilation, more so than normal windows, keeping the interior cool, comfortable, and healthy even when it is raining outside. They are not impacted by the direction of the wind, unlike casement or awning windows.

For ventilation in spaces with higher ceilings, louvre windows can be fitted at any height. These louvres can still be simply manipulated using a convenient map-rod.

  • Privacy and Security

Louvre windows offer a high degree of privacy while providing excellent ventilation. For increased seclusion, Louvres are available in a range of frosted and coloured glass options.

Moreover, they can be slanted at angles that guarantee occupant privacy without obstructing the entry of fresh air. For of this, they are especially well suited for private areas of the house like bathrooms and bedrooms.

  • Natural Light

Louvre windows are excellent for regulating the amount of light that enters a space. They let home occupants to experience natural sunshine without the negative effects of direct, intense sunlight, unlike ordinary windows, when made of clear glass or left totally open.

In contrast, energy-efficient windows with frosted or coloured glass louvres can be used to reduce and regulate the amount of light and heat that enters your home.

  • Easy Cleaning

Conventional windows are difficult to maintain and get dirty easily. Louvre windows also have the advantage of being much simpler to maintain than many other window styles.

The louvre blades can be cleaned from the inside by simply tilting the slats open 180 degrees. This is especially helpful for windows on higher floors that could be challenging to reach from the outside.

Final Thoughts

Moving flaps were introduced into louvres to control flooding and lessen hydrostatic pressure on walls of heavy infrastructure like dams, aerodromes, and aeroplanes.

They are incredibly effective in industrial design for bringing in outside air, purifying the air inside, and expelling stale air. They work in conjunction with mechanical components to offer an efficient, cost-effective industrial ventilation system. By allowing air in throughout the summer, they also assist in controlling the temperature within the industry. Contact Technalco, the best air filter supplier in UAE.

How You Can Find the Right VAV Manufacturer and How They Can Help?

Are you looking for the best air distribution products manufacturer UAE? The engineer will next choose the precise sizes, types, and configurations of the terminal units that will provide the area with comfort after calculating the building’s cooling/heating load and laying out the VAV system.

There are a number of factors to take into account when choosing single duct or fan powered terminal units, including unit capacities, sound, type, heating requirements & kind, and manufacturer.

What is VAV?

A heating, ventilation, and air conditioning (HVAC) system that provides air at variable quantities or amounts while maintaining a constant temperature is known as a VAV.

VAV HVACs are chosen over continuous airflow systems, which deliver air at varying temperatures, because they offer better temperature control, a longer parts lifespan, less noise, and more energy efficiency.

VAV systems with multiple zones are a development of VAVs. These are made up of numerous VAV terminal units or boxes that distribute air in particular regions of a big indoor environment, like an auditorium.

VAV Equipment Selection:

  • Refer to Noise Criteria Value

Select a VAV box using the following NC values:

  • General offices: NC 30 to NC 35.
  • Open-plan-office areas: NC 40.
  • Conference rooms: NC 30.
  • Auditoriums: NC 30.
  • Lobbies and corridors: NC 40.
  • Executive offices: NC 25 to NC 30.
  • Computer/equipment rooms: NC 40 to NC 45.
  • Classrooms: NC 25 to NC 30.

When a VAV box has a hard duct at its intake, a lined exit plenum, and a flexible duct between its plenum and diffusers, discharge noise is rarely a problem. The maximum rating of a VAV box placed atop a typical acoustical ceiling should typically be no more than 5 NC higher than the ideal room rating to account for radiated noise. For instance, a general office with a desired NC level of 30 should not have a maximum VAV box rating of NC 35.

  • Ensure Maximum Airflow matches Required Minimum Airflow Capacity

Heating airflow often has the lowest airflow. The design minimum airflow may be considerably less than the airflow offered by a vendor’s product since velocity can be challenging to measure precisely with varied airflow rates. As long as the vendor’s controls allow for 0 cfm as the lowest airflow option, this is allowed.

This essentially means that a VAV box will cycle on and off as needed to maintain the room’s temperature. Although it might not be ideal, this is frequently the only choice.

  • Calculate Total Pressure Drop

Selection should be aided by total pressure decrease, not only vendor-listed static-pressure drop. Total pressure drop should not exceed 0.5 in. wc, with the exception of critical noise applications (NC 25 or below), for which static-pressure values should be input progressively lower into a selection programme until a desirable alternative is found. Following is a formula for calculating total pressure drop:

Delta TP = delta SP + delta VP


TP = total pressure drop
SP = static pressure
VP = velocity pressure
Delta TP = delta SP + [(Vin ÷ 4,005)2 – (Vout ÷ 4,005)2]

The decision about a VAV box is independent of the controls supplier. It is possible to factory-install third-party controllers on a VAV box. While it might not save money, it does shorten the time needed for procurement by delaying field installation. Coordination before building is necessary.

Tecnalco: VAV Manufacturers in UAE

Being one of the top VAV manufacturers in UAE, Tecnalco units are designed to precisely measure and control air volumes in response to zone-specific requirements for a given room temperature.

The terminals in a CAV application keep the required constant airflow constant regardless of the inlet static pressure. The terminal units in a VAV application regulate the room’s air volume in accordance with the necessary cooling load. In both new and retrofit projects, the VAV or CAV terminals can be utilised for supply or return air applications.

Things to Consider While Selecting an Air Performance Louvre

Louvers appear straightforward—they are only blades in a frame—but there are several crucial aspects to take into account when selecting one for a particular application. Are you looking for the best HVAC air distribution products in UAE? Tecnalco Aluminium Technical Engineering Factory is your right option for it.

In this blog, we go through few fundamental things to think about while selecting the appropriate louvre for the job.

What are Louvers?

Since the Middle Ages, louvres have been employed in construction openings to let air into a structure while keeping out unwelcome elements like water, birds, and garbage. Louvers are now used by architects not just to create eye-catching and distinctive exteriors but also as the first line of defence against water damage to HVAC systems and ducting.

Maximizing the advantages of louvre design and function requires a basic understanding of performance parameters early in the selection process. This method of choosing louvres promotes optimal HVAC system performance and lessens the need for more expensive repairs due to damage to air handling equipment. Select the louvers from the best intake and exhaust air louvre manufacturers in UAE.

  • Protection

The louvre should be made to stop rain and debris from entering your HVAC system. Here, a number of things are involved. A louvre should offer protection, but how much protection is required depends depend on how it will be used. The ability of common louvres to reject water from mild rainfall can be evaluated for water penetration. Testing for wind-driven rain will be necessary for severe weather louvres.

  • Performance

The louvre should pose as little impediment as possible to airflow through its open area. All louvres will offer some resistance; however hurricane and severe weather louvres will offer greater resistance than regular louvres. Pressure drop, or the loss of pressure when air travels through the louvre, is the term used to describe this resistance.

The air performance of the louvre is specifically impacted by factors including free area, face velocity, and system effects like ductwork. This short article from our Condenser series, Air Performance and Keeping the Flow, will help you brush up on air performance.

  • Aesthetic

Louvers should complement the design of the building. Regardless of where they are installed, they should look beautiful. Both personal preference and the overall aesthetic of the project will play a role in this choice. To ensure that each louvre fits your expectations, manufacturers offer basic colours and color-matching alternatives. Any louver’s finish adds colour, but over time, it may start to lose its lustre.

Any finish can become damaged by sunlight, and the louver’s colour can deteriorate. You must select a finish that can withstand salt spray if your louvre will be installed in a coastal area. How long it maintains its original colour will depend on the type of finish you use.

  • Airflow Direction

The direction of airflow should be your next priority. You must determine whether the louvre will cover an intake point or an exhaust point on your building if it will be utilised for ventilation.

Louvers designed for various types of flow will have features that set them apart from exhaust louvres. You must take into account how the louvre rejects water and other undesirable materials since they draw air into the system.

  • Blade Styles

The louvre is made up of blades, and different applications will require different types of blades. Louvers can have either stationary or adjustable blades, or a combination of both.

The possibilities of the louvre are determined by the blade profiles; choose straight profiles for air performance, baffle profiles to prevent water infiltration, or chevron profiles for the greatest wind driven rain protection.

  • Air Volume and Face Velocity

The amount of air flowing through the louvre is referred to as air volume and is measured in CFM (cubic feet per minute). The air flow across the face of the louvre is measured in terms of face velocity. FPM(feet per minute) is often used to express face velocity.

The air performance of the louvre, which determines how the louvre manages air flow, may be determined using these two variables. All louvres depend on air volume and face velocity.


Although each application may require further consideration, these ten qualities are crucial. The application may also be influenced by external circumstances, such as the wind speed in the vicinity of the louvre. Before selecting the louvre, compile a comprehensive list of criteria and considerations.

Why You Should Always Have a Whole House Humidifier

Next to temperature, humidity plays a significant role in deciding how comfortable your house is. Because of this, people experience a significant increase in warmth and comfort in houses that employ whole-house humidifiers.

But whole-house humidifiers offer much more than just increased comfort; they also do a fantastic job of preserving our health. Having amazing hvac air distribution products in UAE, we’re going to discuss ways why getting a whole-house humidifier can benefit you and your family’s health.

What is a Whole House Humidifier?

Your home’s heating system is directly connected to a humidifier that increases humidity throughout the house. Whole home humidifiers come in a variety of designs, but they all work to add water vapour to the air in your home. A humidistat, a device that measures the moisture in the air, can be used to monitor and regulate the level of humidity in the air.

Benefits of Having a Whole House Humidifier:

  • Better Sleep

Minimal humidity indoor air will make Your soft palate dry which can start or worsen snoring. The throat, nasal passages, and soft palate can all be moistened by a whole-house humidifier.

In addition, it might lessen allergies and congestion, both of which contribute to snoring. Your family may sleep better also if there is less snoring, better general comfort, and easier breathing.

  • Better Health

Adding moisture to the dry air in your home may also aid in limiting the transmission of airborne viruses like cold and flu. In simpler terms, in drier air, viral droplets dissolve into tiny particles more quickly and float longer, increasing their chances of infecting the occupants of your home.

A humidifier may also help some people’s allergies and asthma symptoms, though you should always seek medical advice before using one. A poorly kept humidifier can spread mould or germs, aggravating allergies and asthma. So be careful to keep up with routine maintenance.

  • Increases Lifecycle of Your Furniture

Your furniture will lose moisture as a result of dry air. Your furniture may begin to fracture as a result, especially if it is made of wood.

However, you need to be concerned about more than simply your furnishings. Without a whole-house humidifier, the dry air can also cause window frames and hardwood floors to split or fracture.

  • It is noise-less

A whole-house humidifier also has the benefit of being almost noiseless, which results in a tranquil home humidification procedure. The mechanism is concealed so that no one is even aware that it exists.

Having used a portable humidifier, you are aware that it is difficult to conceal. It is not a part of your HVAC system; it is a distinct piece of equipment. A whole-house humidifier’s aesthetic feature allows you to hide your home humidifier from friends and family while still increasing the air quality in your residence.

  • Eliminates Static Electricity

High levels of static electricity are connected to dry air, and they can accumulate on your hair, clothes, and other surfaces.

Everybody has experienced the aggravation that comes with static-filled hair and how it may ruin our appearance. Use a humidifier to carefully manage and achieve the ideal humidity levels in your home while controlling static electricity.

5 Common Types of Damper Systems

There are many volume control damper manufacturers in UAE. The challenge is to choose from different types of damper systems. That said, this article is for you and can really help you make the right choice.

Buildings with numerous rooms, like offices or schools, may have huge and intricate HVAC systems. To supply air to each of these regions, more than just ductwork will be required. Dampers are used in this situation. Devices with blades enclosed in a square or rectangular framework are called dampers. The style and type of the damper can affect how this design is constructed. For example, some dampers may have a rounded frame to fit into ducting that is rounded. You will also find Fire damper manufacturers in the UAE who are there to provide you with high-quality dampers at a budget-friendly price.

There are several distinct types of dampers, each of which has a particular function despite having a similar design. The five types of dampers that are frequently encountered in HVAC systems are listed below.

1. Control dampers

The airflow through the system is regulated by control dampers that are positioned at various locations in the ductwork. These dampers can also be modified for usage in air mixing zones to heat and cool the air. Many times, throughout the day, control dampers will completely open or completely close their blades to fulfil their task.

2. Balancing dampers

Rooms connected to the ductwork have balanced dampers installed to control air pressure. Uneven air pressure can result in minor inconveniences for residents like slamming doors or sporadic air rushes, but it can also result in more serious issues for the overall system. An unbalanced space may be harder to heat or cool, which puts an excessive amount of stress on the air handling devices.

Technicians balance dampers by changing the angle at which the blades of the damper are angled while measuring the air pressure in the space. The blades of the balancing damper are locked in place to preserve the required air pressure once the proper air pressure has been identified. You can unlock them for future alterations.

3. Backdraft Dampers

To limit airflow to one direction only, backdraft dampers are fitted in particular locations within the duct system. Each blade of these dampers has a shaft attached to one end of it. The blade is transformed into a flap in this design, and it only opens when the air is moving in the desired direction.

The blades of a backdraft damper will close if no air is travelling through them or if air starts to move in the opposite direction. Installing a counterweight in a backdraft damper might help or hinder the opening action. These dampers are not equipped with actuators.

4. Multi-Zone Dampers

Multi-zone dampers are utilized in structures with a single air handling unit, such as modest office buildings or single-building schools. These are substantial assemblies of dampers, each of which is connected to a different zone. Multi-zone dampers are duct-connected devices that regulate the airflow throughout the entire system. A multi-zone damper will have several actuators, each of which will control a different zone. These dampers are frequently sold as a whole package with the air handling unit.

5. Industrial Dampers

Industrial dampers are made to stand up to extreme air pressures and constant temperatures of over 250°F. To survive harsh environments, they are constructed from thick gauge materials, mainly steel. For ultimate durability, each component is securely welded into place.

These dampers are frequently used in power plants and manufacturing plants, sites with significant airflow requirements. The industrial ones are the heaviest available dampers.


There are various types of dampers available, and each type has a specific function. With the exception of the single multi-zone damper, which is installed with a single air handling unit, your HVAC system may need that all of these dampers work together. It’s crucial to understand what each damper works and how it fits into your HVAC system even though you will probably use all of these dampers.
