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.

Direct-Drive Duct Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. 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.

Enclosure-Cooling Fans
Protect equipment in enclosures and cabinets from heat. All of these fans are reversible to exhaust hot air out or draw cooler outside air in through a filter that removes dirt and dust. They have UL recognized components.
Replacement filters are sold separately.
