CENTRIFUGAL FANS
Centrifugal fans are sometimes called radial fans or centrifugal blowers. Centrifugal fans discharge air at a 90-degree angle (perpendicular) to the air intake. They have a motor driven hub which contains impellers that throw off air into the fan housing that is then directed to an outlet.
There are also EC or electronically commutated centrifugal fans combine the best features of AC fans and DC fans. While they are powered by a brushless EC motor, the fan rotors are controlled by an assembly of printed circuit boards. EC centrifugal fans auto adjust the power consumption and hence are energy efficient.
