180 mm Fans | McMaster-Carr

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.

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.

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.
