A Centrifugal Fan is made available by us that is also known as axial fans, constant-volume devices, meaning that, at a constant fan speed, a centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that the air velocity in a system is fixed, but the actual mass of air flowing will vary based on the density of the air. The centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid.
