12" Blade Diameter Fans | McMaster-Carr

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.

U.S. Navy Wall-Mount Fans

This fan meets U.S. Navy specification MIL-DTL-68. It has a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. It also has an open dripproof motor enclosure for relatively clean, dry, indoor locations.

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 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.

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 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.
