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.
Battery-Powered Portable Fans
Cool down areas where you don't have an outlet—these fans are lightweight and battery-powered so you can tote them anywhere. The battery and charger are sold separately.
Fans that cannot be sold outside the United States are restricted due to product regulations.

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.
