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 louvers create a weather-tight seal when they're turned off. The louvers open automatically on startup and spring closed when not in use.
Weather hoods (sold separately) help extend the life of your exhaust fan by protecting it from harsh weather, such as severe wind, and debris.

Wind-Driven Roof-Mount Exhaust Fans
Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required. They are also known as turbine ventilators. Mount fans on your roof away from wind obstructions.
Optional mounting bases are sold separately.
All bases have a square bottom, round top, and flashing to simplify installation.
To Order: For slope bases, please specify pitch: 1/12-11/12 in increments of 1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is 5/12.
Surface-Drying Fans
Dry large flat surfaces such as floors with a concentrated stream of air.

High-Flow Low-Pressure Compressed Air Blowers
Also known as regenerative blowers, use these to produce high-flow compressed air with low pressure or vacuum to operate pump drives, lift tables, and conveying systems. Compressed air blowers are also used for drying, exhausting, and aeration.
Air circulates inside the blower housing to compress air, which generates pressure or vacuum. Single-stage blowers circulate air once and then exhaust. Two-stage blowers circulate air twice and then exhaust, creating higher pressure or vacuum than single-stage blowers with the same horsepower.
Inverter-rated blowers have a motor that can run at slow speeds without overheating, so they can be used with a motor speed control (variable frequency drive).
