BLOWER WHEEL/IMPELLER RTH
A blower is a centrifugal fan. It is a mechanical device for moving air or other gases. Blowers 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 fan", or "squirrel-cage fan" (because it looks like a hamster wheel). These fans increase the speed and volume of an air stream through rotating impellers.
Pumps and fans of various types and sizes are used in all kinds of restaurant equipment. The main internal component of these pumps and fans is the impeller. The impeller is a rotor blade designed to increase the pressure and flow of air, gases or fluids.
