Axial Fans - FAQ
1) Where are axial fans commonly used ?
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.
Centrifugal Blower - FAQ
1) What is the difference between ID fan and FD fan ?
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 system are 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 Fans for 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 is a 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.
