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
Belt-Drive Upblast Roof-Mount Exhaust 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. 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. Fans are AMCA (Air Movement and Control Association) rated.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
