About Exhaust Fans

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.

Direct-Drive Wall-Mount Exhaust Fans
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.
Fans with an open dripproof motor enclosure are for relatively clean, dry, indoor locations. Use a collar (sold separately) to connect these fans to a louver.
Fans with louvers create a weather-tight seal when they're turned off. The louvers open automatically on startup and spring closed when not in use.
Weather hoods (sold separately) help extend the life of your exhaust fan by protecting it from harsh weather, such as severe wind, and debris.

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