What is a bathroom fan motor?

A bathroom fan motor powers the exhaust system typically installed in the ceiling of a bathroom to circulate air and steam. The bathroom fan motor operates the fans that help to remove odors and moisture and prevent condensation on the bathroom walls that can potentially produce mold.

Exhaust fan blades attached to the bathroom fan motor are connected to duct work within the home or business that provides air flow to circulate. Most bathroom exhaust systems also have a roof cap that removes moisture and air out of the home or business. Without a roof cap, moisture, condensation or mold develop in the attic.
