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

Window-Mount Office Fans
Draw fresh air in or push stale air out of your windows. Reverse airflow with the flip of a switch. Side panels expand to fit the width of your window.

Dust-Resistant Direct-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. 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.
Collars and louvers are sold separately. Use a collar to connect a wall-mount exhaust fan to a louver.

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.
