A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. 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.A centrifugal blower is a motor or pump that propels air, and it moves the air inside the blower, and at a 90-degree angle, it pushes it out. The two chief elements of this blower are the motor and the impeller. The impeller pulls out the air in contradiction to a propeller which forces the air
