Direct-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. 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. All have an open dripproof (ODP) motor enclosure for relatively clean, dry, indoor locations. They also have a wire mesh inlet guard to protect the fan from debris.

Exterior-Wall-Mount Exhaust Fans
120/230V AC, Single Phase (Hardwire)—Open Dripproof (ODP) Motor Enclosure
 |
Fans with an open dripproof (ODP) motor enclosure should be used in clean, dry, and indoor locations. You can use these fans with or without duct. To use them with duct, you'll need an angle ring (not included).
Direct Drive—Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain.
Grilles—Grilles (sold separately) have fixed blades.
Louvers—Louvers are gravity operated. The blades open when air flows and close when it stops, preventing backdrafts.

Direct-Drive Downdraft Roof-Mount Exhaust Fans
 |
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.

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.
