Difference between Axial Fans and Centrifugal Fans
The common differences between the Axial Fans and Centrifugal Fans.
The structure of axial flow fan is very basic. The fan blades are installed on the circumference of the rotor hub. The blades rotate to blow the air flow in a direction parallel to the rotor axis. The rotor blade assembly is powered by an electric motor. The entire assembly of the motor, rotor and blade is installed in the housing to prevent dust, debris, etc.
Unlike the axial flow fan, the blades of the centrifugal fan are installed on the rotor along the radial direction. The blades are perpendicular to the rotor axis, so when the blades rotate, the air is discharged in the radial direction. Due to centrifugal action, the air circulates and is discharged radially.
