F4-72-A Centrifugal Fan

The 4-72 series centrifugal fan is a high-efficiency and energy-saving centrifugal fan. Its aerodynamic performance is excellent due to the use of airfoil-type blades, curved impeller front plates, and a conical inlet collector. This design has been widely used in China’s industrial development for many years.

The fan is available in four drive types: A, B, C, and D. Type A is a direct drive with the impeller directly connected to the motor. Type B uses a belt drive with the pulley located between two bearings. Type C uses a belt drive with the pulley mounted on the outer side of the bearing in a cantilever arrangement. Type D uses a coupling to connect the impeller and the motor.
