Choose an exhaust fan based on the size of your space and how often you want to refresh the air.
Belt-Drive Wall-Mount Exhaust Fans with Louvers
 |
These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. Use these fans to draw stagnant and humid air out of a room or area.

Dust-Resistant Direct-Drive Wall-Mount Exhaust Fans
 |
Style 5 |
Better suited for dirty, dusty, and damp environments than standard direct-drive fans, these have a totally enclosed motor enclosure. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area.

Exhaust Fan Collars—Collars and louvers are sold separately. Use a collar to connect a wall-mount exhaust fan to a louver.
Direct-Drive Upblast Roof-Mount Exhaust Fans
 |
Style 2 |
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
