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 Duct 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. Also known as axial duct fans, these install inline in ductwork for use as an exhaust, supply, or booster fan. All fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Belt-Drive Hazardous Location Duct Fans
These fans have a motor that is UL listed for Class I, Group D and Class II, Groups F and G hazardous environments. All are belt-drive fans that are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. They install inline in ductwork for use as an exhaust, supply, or booster fan. The fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
