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.
Belt-Drive Mobile Floor Fans
Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged.
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.

Hazardous Location Floor Fans
Often used in welding shops and oil refineries, the motor in these fans is rated as safe for use around flammable and combustible gas, vapor, and dust. As a belt-drive motor, it’s quieter than direct-drive motors and has a longer life span because its components are replaceable. The motor is totally enclosed for protection in dusty and damp environments. These fans are freestanding, so there’s no mounting required. They have wheels for rolling into place before they’re hardwired, but don’t allow for movement once they’re in use.

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.
