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.

Economy Direct-Drive Mobile Floor Fans with Tilt Stand
Tilt fans to direct air where it's needed. These direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.
30" and 36" blade diameter fans can also mount to the wall and ceiling.

Office Tower Fans
Because they have a small footprint, these fans are good for small areas or places where clutter is a concern. The remote control includes multiple timer options to automatically turn the fan on and off. Move these fans wherever you need them.

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.

Belt-Drive Wall-Mount Exhaust Fans
Use these fans to draw stagnant and humid air out of a room or area. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. All have an open dripproof motor enclosure for relatively clean, dry, indoor locations.
Collars and louvers are sold separately. Use a collar to connect a wall-mount exhaust fan to a louver.

Fume Hoods
Pair these hoods with an exhaust system to contain harmful fumes, vapors, and gasses while venting them away from work spaces—they protect users from inhaling or coming in contact with them. To access the enclosed space, these hoods have an adjustable sliding window, which also lets your exhaust system pull air from the outside.
Polypropylene hoods are nonconductive. They’re also translucent, so they let in more light than polyethylene hoods for added visibility.
