Backward Curved Centrifugal Blower 800 - 90000m3/h Boiler Blower Fan

Backward curved high capacity industrial blower fan used for boilers

The blades of the centrifugal blower fan can be divided into three forms: back bending, front bending and radial according to the size of the outlet installation Angle. The bending direction of the back-bending blade is opposite to the rotating direction of the impeller, and the outlet installation Angle is less than 90 degrees. The outlet direction of the radial blade is radial, and the outlet installation Angle is equal to 90 degrees. The bending direction of the forward-bending blade is the same as the rotating direction of the impeller, and the outlet installation Angle is greater than 90 degrees.

Centrifugal fan can be made into right - handed and left - handed two types. From the motor side facing: impeller clockwise rotation, known as the right rotation fan; Counterclockwise rotation is called left rotation.
