How do centrifugal fans work?

Designed to move gases or air in a specified direction, motor driven internal rotating impellers draw air in and increase the output volume and speed of the air stream. The curved blades use kinetic energy moving against resistance and ensuring a constant speed. Centrifugal fans or blower fans as they are otherwise known, change the direction of air, generally at a 90° angle. This is made possible by the fan being mounted around a hub, gas or air enters the side of the drum and it moved over the blades to the exit point, whilst the resistance offered by the housing and duct helps increase volume and speed.

What are centrifugal fans used for?

Widely used in the HVAC industry these types of fans are used for moving gas or air in buildings, vehicles and ventilation systems. They can be used to move air or gas into an enclosed space or out of it. Due to their design they are able to create a higher pressure of air flow when compared to axial fans. Examples of application include:

• Dust collection

• Cooling

• Air re-circulation

• Boilers

• Automobile ventilation

• Electronics
