Quick Summary

A centrifugal fan is a type of fan that operates on the principle of a centrifugal pump. It is a machine that uses centrifugal force to move air or other gases.12

In a centrifugal fan, air enters the center of a rotating impeller and is then forced outward radially into a spiral casing. From this casing, the air is directed to a discharge pipe. This design allows centrifugal fans to generate a significant pressure gain, making them suitable for applications requiring a small flow rate but high pressure. They are driven by various power sources, including electric motors or turbines.3

In centrifugal fans air is led through an inlet pipe to the centre, or eye, of the impeller, which forces it radially outward into the volute, or spiral, casing from which it flows to a discharge pipe.
