About Exhaust Fans
More
About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.
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 motor enclosure for relatively clean, dry, indoor locations. They also have a wire mesh inlet guard to protect the fan from debris.
Fans that cannot be sold to California are restricted by local energy efficiency requirements.

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.
Fans with an open dripproof motor enclosure are for relatively clean, dry, indoor locations. Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.

Dust-Resistant Direct-Drive Wall-Mount Exhaust Fans
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.
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
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.
Fans that cannot be sold to the listed areas are restricted by energy efficiency requirements.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Direct-Drive Downdraft Roof-Mount Exhaust Fans
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.

Hazardous Location Upblast Roof-Mount Exhaust Fans
With a UL-listed motor, these fans can be used in hazardous environments with combustible gases and dust to draw stagnant and humid air out through your roof, forcing it up and away from its surface.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
Belt-drive fans are quieter and last longer than direct-drive fans because their components can be replaced if they’re worn or damaged.

Hazardous Location Exhaust Fans
These fans have a motor that is UL listed for hazardous environments. Use them to draw stagnant and humid air out of a room or area.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Add a collar (sold separately) to connect a wall-mount fan these fans to a louver.
Belt-drive fans are quieter and last longer than direct-drive fans because their components can be replaced if they’re worn or damaged. They come with collars, so you can connect these fans to a louver.
Fans that cannot be sold to California do not meet energy efficiency requirements.
