Form classification of centrifugal fans

Feb 22, 2021

The blades of centrifugal fans can be divided into three types: backward bending, forward bending and radial according to the size of the outlet installation angle. The bending direction and the backward curved blade impeller rotation direction of the opposite, outlet mounting angle less than 90 degrees; outlet radial direction of the radial blade, mounting angle is equal to the outlet 90 degrees; same bending direction of the front curved blades rotating direction of the impeller , The outlet installation angle is greater than 90 degrees. Centrifugal fan Centrifugal fan can be made into two types of right-handed and left-handed. Viewed from the side of the motor: the impeller rotates clockwise, called right-rotating fan; counterclockwise, called left-rotating .
