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.
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.

Dust-Resistant Direct-Drive Wall-Mount Exhaust Fans
Better suited for dirty, dusty, and damp environments than standard direct-drive fans, these have a totally enclosed motor enclosure. 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.
Collars and louvers are sold separately. Use a collar to connect a wall-mount exhaust fan to a louver.

Chemical-Resistant Blowers
For resistance to chemicals as well as corrosion, these blowers have a plastic housing. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting. All blowers 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.PVC plastic housing offers greater chemical resistance than the fiberglass housing. It resists strong oxidizing acids such as sulfuric acid but will not withstand contact with perchloric acid.

Hazardous Location Chemical-Resistant Blowers
These blowers have an explosion-proof motor that is UL listed and CSA certified for Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups F and G hazardous locations. For resistance to chemicals as well as corrosion, they have a plastic housing. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting. All blowers have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
