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.
Edge-Flow Equipment-Cooling Blowers
For use in tight spaces where other equipment-cooling blowers won't fit, air enters through the center of these blowers and then expels along the edges. They create a more concentrated stream of air than equipment-cooling fans to blow away the heat generated by electronic equipment, induction heaters, and high-wattage bulbs. Use them to keep heat-sensitive equipment such as electronic components cool.
Round blowers are also known as motorized impellers.
