BLOWER MECH. CONT. VARIABLE

Blowers are used in restaurant equipment to diffuse heat, aid in convection, and circulate cold air. 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.

Controls of all kinds are integral parts of restaurant equipment operation. A control is a switch or other device by which a machine is regulated. A control may be manual or automatically operated. An electro-mechanical control typically consists of multiple relays, timers, and/or counters wired together on an enclosure panel. Electro-mechanical control is also referred to simply as "Relay Control", which is a more accurate term since solid state electronic relays, timers, and counters are standard components. Contactors, motor and compressor starters, valves, thermostats, and other output devices are used to turn on/off motors, indicator lights, heating elements, and other components used in the equipment.
