Centrifugal Fans

A centrifugal fan is a device used to move air or other gases. In a centrifugal fan, the inlet gas enters the fan along the axis of rotation. The gas is then diverted by a set of rotating vanes until the exit air is directed radially outward, away from the axis of rotation. The gas is captured in the casing of the fan and directed out of the exit of the fan unit. Because the look and orientation of the fan wheel resembles that of a hamster wheel, centrifugal fans are often referred to as squirrel-cage fans.
