Axial fans move large volumes of air effectively and efficiently and are commonly used to cool both small and large spaces. They can cool electronic equipment or computer rooms. They can be used in HVAC operations, in ac condensers, heat exchange units, or for spot cooling in industrial systems.
2) What is the purpose of an axial fan?
Axial fans are generally used for cooling applications like the ones mentioned below: Process cooling in systems or machinery. cooling of Power transformers and generators and industrial equipment. Ventilation in warehouses, factories, foundries, laundries, garages, equipment rooms, and engines.
3) How do axial fans move air?
Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction. Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow.
4) Where is the best fan for air circulation?
However, fan placement matters. Place your fan so that it faces the opposite wall from where most of the activity takes place in your space. This approach will drive the air to the surface, where it will bounce off, mingling with the rest of the air and cooling the space.
5) What is static pressure?
The pressure difference across the front to the back of the Fan generated by the discharged air, which is unaffected by air flow speed.
Unit: Ps (Pa)
1.The air pressure across the front to the back of the Fan does not change when the Fan is stopped.
2.Static pressure (Ps) is generated at the front of the Fan when it rotates.
6) What is the flow rate?
This is the amount of air that passes through the Fan in a certain time (1 min). In other words, it is the amount of wind that the Fan produces.
Unit: Q (m3⁄min)
7) How can you protect Axial-flow Fans from burning?
All VAYUVENTS Axial-flow Fans are provided with either impedance protection or thermal protection.
UL, ATEX, EN, and IEC standards require all equipment that uses a motor to be equipped with a device that protects the motor against overloads.
8) How many types of axial flow fans are there?
Axial flow fans are a type of fan that moves air along the axis of the fan. The most common axial flow fans are propeller-type fans. They are most often used in ventilation, heating, and air conditioning systems. The fan blades move air from the back of the fan to the front of the fan. This type of fan is used to move air from one space to another, or to move air around a space. Axial flow fans are often used in conjunction with diffusers or grilles to direct the airflow in the desired direction.
9) What is the principle behind the axial flow fan?
The basic principle of operation of the axial fan is that the direction of air flow is parallel to the rotor shaft. The blades of the fans force air linearly to the shaft. Axial flow fan are known to create a high flow rate, and they are able to achieve a bigger volume of air flow.
10) How do you calculate CFM for axial fans?
To calculate multiply length x width x height of growing area e.g. A room that is 8' x 8' x 8' will have a volume of 512 cubic feet. Your extraction fan should be able to adequately exchange the air in an indoor garden once every three minutes. Therefore, 512 cubic feet / 3 minutes = 171 CFM.
The key difference between a forced draft and an induced draft fan is, FD fan forces outside air into the heating system whereas an ID fan draws flue gases from the system out into the atmosphere.
2) What is a forced draft fan?
Fans that are used to pressurize a space or create mechanical air pressure in a systemare referred to as forced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific positive pressure.
3) How does an induced draft fan work?
Forced-draft fans focus the pressure and volume at the outlet of the fan to push air through a system, creating positive air pressure. Industrial-induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system.
4) Which fan is used in high temperature?
High-Temperature Centrifugal Fansfor Industrial Applications. High-temperature process airstreams are conveyed using specially designed high-temperature centrifugal fans that can handle temperatures of up to 1800 degrees F. Many industrial processes rely on high-temperature process heat.
5) How centrifugal fan works?
A centrifugal blower isa motor or pump that propels air, and it moves the air inside the blower, and at a 90-degree angle, it pushes it out. The two chief elements of this blower are the motor and the impeller. The impeller pulls out the air in contradiction to a propeller which forces the air.
6) Why do we use centrifugal blower?
The centrifugal blowers areused in industries where there is a requirement for larger volumes of airflow with high pressure. They are highly useful in industrial processes like conveying material in dust collector systems, combustion air for burners, drying and cooling, general ventilation, and circulation of air.
7) What determines the minimum horsepower requirement for vayuvents centrifugal and industrial fans?
Minimum horsepower for centrifugal and industrial fans is based on either the operating brake horsepower or the minimum starting horsepower of the fan. Operating brake horsepower is an obvious limit to the minimum motor horsepower, since the motor horsepower must exceed the operating brake horsepower for the fan to work. Minimum starting horsepower is based solely on the horsepower required to get the fan wheels rotating.
8) What is the max flow and pressure that a vayuvents blower can produce?
By utilizing a unique belt drive system that increases the blower speed by more than 5 times faster than the motor speed, we can produce pressures of up to 100” W.C. (slightly over 3.5 PSIG) and flows of up to 1500 CFM.
9) What is the difference between Backward and forward curved fans?
The forward curved impeller is therefore much quieter than the backward curved impellerand, due to the higher number of blades, gives a noise spectrum with much wider bandwidth and therefore lower energy in any part of the spectrum when compared to the backward curved impeller.
10) Why Backward curved blades are used?
The benefit of using a backward curved motorized impeller is that it does not have a stall point on its characteristic. This means that there is no point on the fan characteristic curve that it should not be operated.
It allows hot air to escape and cool air to enter the space. This can also help prevent super-heated attics, which can also impact your heating and cooling costs. Overall, ensuring proper ventilation will help your factory be more comfortable during the entire year.
2) How many roof ventilators will I need?
That obviously will depend on both the size of the building(s) in question and their purpose. For example, a factory generating a lot of heat, fumes, and dust will naturally require a more substantial system than say a storage warehouse or community hall.
The natural ventilation specialists at Vayuvents will be only to happy to inspect your facility, talk to you about your needs and then tell you exactly how many ventilators you will need.

4) Does a Motorised Roof extractor fan remove hot air?
To answer this question, it's important to know a little about how a kitchen exhaust fan works. An exhaust fan removes grease, smoke, and cooking odors from your home. It also removes hot air from your Factory , Industry, wharehouse.
5) What are the benefits of Powered roof ventilators?
Be it a factory, warehouse, or other commercial facility, a professionally ventilated building can reduce trapped heat and dust, making for a cooler, cleaner workplace.
VayuventsMotorized Roof ventilations systems also help to remove moisture, condensation, smoke, fumes and pollution particles in the air, replacing them with clean, fresh air, and reducing the likelihood of corrosion and rust.
6) What are Mechanical roof vents?
Technically, these are any vents that allow air to pass through the attic or roof deck. Of course, many vents are actually installed on the eaves, but a number are directly attached to the roof itself, depending on the design. Roof vents are so important to the health of a house that they are typically required by local building codes for any new projects.
7) What is best roof ventilation?
In most cases, we recommend Axial Fan for intake and a Motorised Roof vent for exhaust. For Factories that cannot have a ridge vent, Powered Roof Vent are generally the second best option for exhaust.
8) Types Of Roof Vents?
What is ventilation, anyway? According to Oxford, ventilation is the “provision of fresh air to a room, building, etc.”
It’s out with the old (air) and in with the new (air). In roofing just like in life, this is very refreshing and important strategy to have!
Understanding how air naturally moves helps us realize why both intake and exhaust play a critical role in a roof’s venting ability. And knowing how the two work hand-in-hand is important before choosing which of types of roof vent systems are best for your factory and budget.
Exhaust; Let That Stale Air Out
According to West Texas A&M University, Physics Professor Christoper Baird, “heat does not rise, hot air rises. (source)” For the purposes of venting your attic space, this is valuable because it is the hot air, which contains moisture, that you want to get out of your attic space.
If the hot air is allowed to stagnant, it can lead to bad-smelling mildew and eventually mold. This is one of key reasons why ventilation is important to your home’s health, as mentioned above.
Because hot air rises, exhaust-style vents are generally placed towards to top of your roof line. The most common exhaust vent used for modern roofing systems is the ridge vent. At Vayuvent, we install a ridge vent for every single new roof unless the home’s style does not allow for it.
Intake; Bring That Fresh Air In
Hot air leaving your attic is important for your home’s health and roof’s longevity, but hot air is generally pretty stubborn! It doesn’t want to leave without being forced out, so we need something to act as a bouncer. Enter: cooler air.
Cool, fresh air (in form of intake ventilation) is the other half of a great venting strategy. The cooler air comes into your attic space via intake vents that are placed lower on the roof line than the exhaust vents mentioned above. Because the cooler air enters underneath the hot air (and because hot air rises), the intake ventilation will help push the stubborn hot air out of the attic space. The cool air, by way of intake style vents (like a soffit) acts as our bouncer.
As long as you have exhaust vents with a large enough surface area, then this cooler intake air will help thrust the hot air out of the home. In a perfect world, it’s all a complete cycle…
9) What is a power roof ventilator?
One technology designed to try to manage this issue is the power Roof ventilator, a type of fan that is typically installed on the rooftop. Its goal is to cool off the space by exhausting the hot air inside and replacing it with cooler air from the outside.
10) Who are the leading manufacturers of roof ventilators in India?
Vayuvents Private Limited is one of the leading roof ventilator manufacturers in India.

Cooling of a transformer is the process of dissipation of heat developed in the transformer to the surroundings. The losses occurring in the transformer are converted into heat which increases the temperature of the windings and the core. Therefore, cooling is doneto dissipate the heat generated in the transformer.
2) What are two methods of cooling a transformer?
• Air Natural (AN) cooling – Cooled by surrounding air. Heat transfer by natural air convection.
• Air Forced (AF) cooling – Forced air circulation using Vayuvents fans and blowers
3) Are Vayuvents fans suitable for 50hz operation?
Yes. All standard Vayuvents fans are designed for 50/60hz operation. Please note that all of the performance data listed on the website is for 60hz operation. For 50hz performance data, please contact that factory.
4) What are the best cooling fans on the market?
Best cooling fan overall: Vayuvents axial Fan.
Best Centrifugal fan: Vayuvents Centrifugal Blower.
5) What is cooling fans in transformer?
Transformer cooling fans aresturdy, Vayuvents weatherproof fans for accelerating the cooling process in oil-cooled electrical transformers. They circulate air around the exterior of the transformer's radiator as oil works its way through the inside to dissipate heat and reduce the operating temperature of the transformer.
The most effective way to remove hazardous smoke, gases, and fumes is at the source (which is the work being welded) via an extraction system. The next best solution is ventilation equipment, although in many instances it is advisable to use both together.
2) What is the purpose of a fume extractor?
A fume extractor is a system that utilizes a fan using negative draft to pull fumes and dust particles in to a contained filtration system. This process removes hazardous particles from the air.
3) How can fume hazards be prevented?
Workers should position themselves to avoid breathing welding fume and gases. For example, workers should stay upwind when welding in open or outdoor environments. . General ventilation, the natural or forced movement of fresh air, can reduce fume and gas levels in the work area.
4) What is the best control for protecting against chemical fumes?
The best ways are to use only chemicals that are not dangerous to breathe, to enclose machines so they do not give off fumes, and to have good ventilation. If you must use a respirator, the ones that protect most completely are respirators with filters or separate air supply.
5) Can high vacuum systems be used for other purposes?
High vacuum systems can be used for other purposes such as extraction of dust and particles from grinding, polishing, dry and wet vacuuming etc.
A dust collector removes dirt, dust, debris, gases and chemicals from the air, providing your factory with cleaner air, which can provide numerous benefits.
2) How does a pulse jet dust collector work?
A pulse jet dust collector is a suction and filtration system. As dust-laden air is drawn into the system, filter media will collect dust, while clean air is discharged from the collector. Compressed air is applied in reverse pulse to clean the filter media.
3) How does a pulse jet bag filter work?
The mechanics of the compressed air pulse and associated induced draft of additional air through a venturi nozzle create a shock wave and ripple effect on filter bags which enhances the mechanical force of the initial blast of compressed air itself to dislodge the dust particles off the fabric.
4) Which force is used to increase the rate of filtration?
Most industrial filtration processes involve the use of pressure or vacuum, depending upon the type of filter used, to increase the rate of filtration and also to decrease the size of the equipment required.
5) What are the benefits of Pulse Jet Bag Filter?
The versatility of the Pulse jet bag filter makes it very useful in a wide range of industries. It is very compact and can fit any size and shape. Similarly, it is most adaptable to external and internal use as well as hot and cold process temperatures. Other benefits include-
Budget-friendly and easy to operate.
These filters can remove particles up to 2.5 microns and has a great level of efficiency.
The screen can work without any interruption even when the cleaning is going on.
Energy Efficiency and minimal maintenance.
