An EXHAUST FAN is a fan which is used to control the interior environment by venting out unwanted odors, particulates, smoke, moisture, and other contaminants which may be present in the air. The fans pull odors, fumes, and moisture from an area of the home, venting them outdoors for removal. The fan uses a motor to turn its blades, which function to pull air out of the space. The stale, humid, or contaminated air is propelled through the exhaust vent, exiting the home. The fans can also be integrated into a heating and cooling system. EXHAUST FAN is made available in various types.
