About Exhaust Fans
More
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 with Louvers
These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. 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. All have an open dripproof motor enclosure for relatively clean, dry, indoor locations. They also have a wire mesh inlet guard to protect the fan from debris.
Fans that cannot be sold to California are restricted by local energy efficiency requirements.

Exterior-Wall-Mount Exhaust Fans
Good when you don't have room to mount an exhaust fan inside your facility, these fans attach to openings in outside walls. Use them to draw stagnant and humid air out of a room or area.
Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain.
Fans with an open dripproof motor enclosure should be used in clean, dry, and indoor locations. You can use these fans with or without duct. To use them with duct, you'll need an angle ring (not included).
Note: Airflow depends on the resistance created by louvers, filters, and ductwork in your system. This resistance, known as static pressure (SP), is measured in inches of water.
Grilles (sold separately) have fixed blades.
Louvers are gravity operated. The blades open when air flows and close when it stops, preventing backdrafts.

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.
