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.
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.
