180 mm Fans | McMaster-Carr

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.

Submersible Equipment-Cooling Fans

Able to withstand submersion in up to 3 meters of water, these fans cool electronics in food processing areas and outdoors. Ball bearings keep them running smoothly and quietly, reducing friction to increase their lifespan. Also known as muffin fans.

High-Pressure Washdown Equipment-Cooling Fans

Cool down electronics in areas that require frequent and intense sanitizing. Rated IP69K, these AC-powered fans withstand harsh jets of water and block dust from reaching their motor. All have ball bearings that reduce friction and heat from operation, extending their life. Also known as muffin fans.

Wet-Location Equipment-Cooling Fan Kits

Cool heat-sensitive electronics without having to hardwire your fan—these kits include the fan, guard, and power cord. They’re IP-rated to withstand dust, light rinses, and other wet environments. The guard prevents accidental contact with fan blades, which helps avoid injury. All have ball bearings to reduce the heat that’s generated from the fans for a longer service life.

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.

Square blowers have UL recognized components and are CSA certified.
