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.

Pedestal Fan Motors
Build your own fan or replace a fan motor. Mount one of these motors directly to a fan column. Four 8-32 threaded mounting studs extend 1" for mounting a fan guard.
View information about motors.
Note: When selecting a fan blade, be sure the rpm and hp are compatible and the shaft diameter of the blade matches the shaft diameter of the motor.

Dust-Resistant Belt-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. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. 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.

Light Duty Direct-Drive Wall-Mount Exhaust Fans with Louvers
These light duty fans are designed for use without duct. They 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 a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

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.

Hazardous Location Exhaust Fans
These fans have a motor that is UL listed for hazardous environments. 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 for less maintenance. Add a collar (sold separately) to connect a wall-mount fan these fans to a louver.
Fans that cannot be sold to California do not meet energy efficiency requirements.

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.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

High-Output Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard blowers can handle. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, drying, ventilating, and exhausting. Blowers that weigh 280 lbs. or less can also be used for material conveying. Blowers with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.
