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.
Hanging Box Fans
Easily hang these fans from your ceiling using the attached bracket and a mounting chain kit (sold separately). They're more powerful than our standard box fans. Made with a heavy duty 12-gauge welded wire mesh guard, these fans will stand up to tough environments. Plastic guard clips help reduce vibration between the housing and the guard, making these fans quieter. They require little maintenance thanks to their totally enclosed, high-efficiency motor and sealed ball bearings.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.

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 a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments. They mount through the wall, so you'll need to cut a hole on the inside of the wall as well.
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.

Direct-Drive Upblast Roof-Mount Exhaust Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

High-Output Spark-Resistant Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard spark-resistant blowers can handle. They have an aluminum housing for spark resistance. 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.
