Light Duty Direct-Drive Wall-Mount Exhaust Fans with Louvers

These light duty fans are designed for use without duct. They 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 a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

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.

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.

Exterior-Wall-Mount Exhaust Fans

Good when you don't have room to mount an exhaust fan inside your facility, these fans attach to openings in outside walls. Use them to draw stagnant and humid air out of a room or area.

Note: Airflow depends on the resistance created by louvers, filters, and ductwork in your system. This resistance, known as static pressure (SP), is measured in inches of water.

120/230V AC, Single Phase (Hardwire)—Open Dripproof (ODP) Motor Enclosure

Image of Product. Front orientation. Open Dripproof (ODP) Motor Enclosure. Exterior-Wall-Mount Exhaust Fans.

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.
