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.

About Exhaust Fans

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.
