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.
Jet-Stream Floor 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 totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.

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.

Hazardous Location Upblast Roof-Mount Exhaust Fans
With a UL-listed motor, these fans can be used in hazardous environments with combustible gases and dust to draw stagnant and humid air out through your roof, forcing it up and away from its surface.
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.
Belt-drive fans are quieter and last longer than direct-drive fans because their components can be replaced if they’re worn or damaged.
