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.

Wide-Flow Equipment-Cooling Blowers

Also known as crossflow blowers, these create a wider stream of concentrated air than other equipment-cooling blowers 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. All have UL recognized components and are CSA certified.
