Industrial Centrifugal Fan and Blower Wheel Types. A centrifugal fan changes the air direction twice as the air moves through the fan (the air turns into the wheel, then turns again into the direction of the ductwork/plenum). Centrifugal fan which is also called as squirrel cage fan because of its hamster wheel design is widely used to move air/gas continuously in industries and commercial applications. This type of fan produces, comparatively (with respect to axial fans), a higher pressure and less gas flow; they are noisier than axial fans.
