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.
About Exhaust Fans
More
Jet-Stream Floor Fans
Often used to cool warehouse aisles and production lines, these fans generate a stream of air that travels farther than air from conventional fans. All have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. They also have a totally enclosed motor enclosure, which 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.
