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.
Blowers
These blowers 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 an open dripproof motor enclosure for relatively clean, dry, indoor locations.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

High-Output Portable Blowers
Blow twice as much air as other portable blowers. These are powerful enough for use with flexible duct, yet light enough to carry from job to job. 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. They rest on the floor with their built-in base or can be mounted on an optional stand (sold separately).

Hazardous Location High-Output Portable Blowers
In addition to blowing twice as much air as other portable blowers, these have an explosion-proof motor that is UL listed for Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups E, F, and G hazardous locations. They are powerful enough for use with flexible duct, yet light enough to carry from job to job. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting. They rest on the floor with their built-in base or can be mounted on an optional stand (sold separately).
