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.

Economy Wall-Mount Fans

Position these wall-mount fans to direct air where it’s needed. All of these fans have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. They also have a totally enclosed motor enclosure, which can be used in dirty and dusty environments.

Wall-Mount Jet-Stream Fans

Often used to cool warehouse aisles and production lines, these fans generate a stream of air that travels farther than air from conventional fans. They have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. They also have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

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.

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.

Direct-Drive Wall-Mount Exhaust Fans with Louvers
These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. 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. All have an open dripproof motor enclosure for relatively clean, dry, indoor locations. They also have a wire mesh inlet guard to protect the fan from debris.

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.

Belt-Drive Duct Fans

Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. Also known as axial duct fans, these install inline in ductwork for use as an exhaust, supply, or booster fan. All fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Belt-Drive Corrosion-Resistant Duct Fans

A 304 stainless steel housing offers good corrosion resistance. All of these belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. They install inline in ductwork for use as an exhaust, supply, or booster fan. The fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Belt-Drive Hazardous Location Duct Fans

These fans have an explosion-proof motor that is rated for hazardous environments. All are belt-drive fans that are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. They install inline in ductwork for use as an exhaust, supply, or booster fan. Fans rated IP56 have a motor enclosure that’s rated for protection in damp, dusty, and washdown environments. UL and CSA standards apply to the motor.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Mobile Evaporative Air Coolers


Also known as swamp coolers, use these air coolers wherever air conditioning is impractical. They take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air. These air coolers have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. All have a NEMA 5-15 plug, which is a standard three-prong plug.
