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.
High-Output Direct-Drive Duct Fans
Produce three times the airflow as standard direct-drive duct fans. All of these direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. All have a TEFC (totally enclosed fan cooled) 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.

Direct-Drive Hazardous Location Duct Fans
These fans have an explosion-proof motor that is UL listed for Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups F and G hazardous environments. All are direct-drive fans that have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. The fans have a TEFC (totally enclosed fan cooled) motor enclosure, which can be used in dirty, dusty, and damp environments.
