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.
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.
Square blowers have UL recognized components and are CSA certified.
Round blowers are also known as motorized impellers.

A galvanized steel housing offers good corrosion resistance. All of these direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. The fans 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.
