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.
Pivoting-Head Portable Fans
Direct air to a specific area, ranging from the floor to the ceiling, by adjusting the head of these fans up and down. They are portable.

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.
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.

Fan Blades
Replace worn and damaged fan blades. Use the included set screw or shaft collar to fasten a blade to your fan's shaft. For difficult-to-remove hubs and fan blades, use fan blade pullers (not included).
Styles A-C blades are for use in low-airflow applications.
