Exhaust Louvers | McMaster-Carr

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.

Roof-Mount Louvers

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts. The felt seal on the face of the blades ensures quiet closing and better protection from the weather.

Also Available: Additional louver sizes. Please select 8061T999 and specify louver dimensions.

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.

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.

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.

120V 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.

120/230V AC, Single Phase (Hardwire)—Totally Enclosed Motor Enclosure

Image of Product. Front orientation. Totally Enclosed Motor Enclosure. Exterior-Wall-Mount Exhaust Fans.

Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments. They mount through the wall, so you'll need to cut a hole on the inside of the wall as well.

Direct Drive—Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain.

Belt Drive—Belt-drive fans are quieter than direct-drive fans. They also last longer because their components can be replaced if damaged.

Corrosion-Resistant Direct-Drive Wall-Mount Exhaust Fans with Louvers

Rust won't be a problem with the durable plastic housing and louvers on these fans. The 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 a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
