Choose an exhaust fan based on the size of your space and how often you want to refresh the air.
Direct-Drive Upblast Roof-Mount Exhaust Fans
 |  |
Style 1 | 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.
Brushless Motor—Fans with a brushless motor have advanced electronic controls that allow them to precisely operate at wide range of speeds, making them more efficient, quieter, and longer lasting than fans with a standard motor.
Cannot Be Sold To—Fans that cannot be sold to the listed areas are restricted by energy efficiency requirements.

Belt Drive
|
Belt-drive fans are quieter and last longer than direct-drive fans because their components can be replaced if they’re worn or damaged.

Direct-Drive Downdraft Roof-Mount Exhaust Fans
 |  |
Style 1 | Style 2 |
 | |
Style 3 |
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. More economical than upblast roof-mount exhaust fans, these draw stagnant and humid air out through your roof and then direct it back toward the roof. 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.
Brushless Motor—Fans with a brushless motor are more efficient than fans with a standard motor. They operate at a wide range of speeds for precise speed control and greater energy savings. They’re also quieter and have a longer lifespan because of their advanced electronic controls.
