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.
