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.
Corrosion-Resistant Direct-Drive Wall-Mount Exhaust Fans with Louvers
Rust won't be a problem with the durable plastic housing and louvers on these fans. The 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 a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Belt-Drive Mobile Floor 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.
Fans with an open dripproof motor enclosure are for relatively clean, dry, indoor locations.
Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.

Wet-Location Enclosure-Cooling Fans
Able to withstand dust and water splashes, these fans are IP54 rated. They protect equipment in enclosures and cabinets from heat. All of these fans are reversible to exhaust hot air out or draw cooler outside air in through a filter that removes dirt and dust. They have UL recognized components.
Optional hoods block dirt and falling liquids from entering enclosures through the fan cutout. Choose the hood that matches the NEMA rating of your enclosure. NEMA 3R hoods protect from light splashing. NEMA 4 hoods protect from jets of liquid, such as washdowns. NEMA 4X hoods protect from jets of liquid and corrosion. Their silicone gasket is FDA compliant for direct contact with food, so they’re commonly used in food and beverage plants.
Replacement filters are sold separately.
