Mount and blade builds2/17/2023 ![]() ![]() Compared to standard axial fans, they can provide similar air movement from a smaller fan package, and overcome higher resistance in air streams.Ĭentrifugal fans use the kinetic energy of the impellers to move the air stream, which in turn moves against the resistance caused by ducts, dampers and other components. They are typically used in ducted applications to either draw air through ductwork/heat exchanger, or push air through similar. These fans move air from the rotating inlet of the fan to an outlet. ![]() ![]() Tiny ones used in computers are sometimes called biscuit blowers. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel). The centrifugal impeller itself is housed in the blue volute (left), and received mechanical power from a VFD-controlled AC motor housed in the blue casing on the right.Ī centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. A high pressure centrifugal fan that is used for supplying air to an aeration tank for an industrial process. ![]()
