High-Output Equipment-Cooling Fans

These fans produce greater airflow than standard equipment-cooling fans. Also known as muffin fans and electrically commutated (EC) fans, they keep heat-sensitive equipment such as electronic components cool. Ball bearings keep them running smoothly and quietly, reducing friction to increase their lifespan. All have UL recognized components and some are CSA certified.

High-Temperature Equipment-Cooling Fans

While standard equipment-cooling fan motors degrade when used in high-temperature areas, these fans run continuously without issue in temperatures up to 190° F. They are made entirely of metal and are lubricated with high-temperature bearing grease. This means they are often used to cool electronics near higher temperature areas, such as near commercial ovens. These fans have ball bearings that reduce friction as they run, extending their life. Their bearings also decrease noise for quiet operation.

High-Pressure Washdown DC Equipment-Cooling Fans

Keep electronics from overheating in places that must be sanitized often. These DC-powered fans are rated IP69K, meaning you won’t damage them with harsh jets of water and they block out dust. For a long life, all have ball bearings that reduce friction and heat as they operate. Also called muffin fans.

Wet-Location Equipment-Cooling Fans

Able to withstand dust and water splashes, these fans are IP rated. Also known as muffin fans, they keep heat-sensitive equipment such as electronic components cool. All have ball bearings to lower the heat that is generated from the fans for a longer service life. They also have UL recognized components.

Square

Quick-Disconnect Terminal Connection—Use fans with quick-disconnect terminals to quickly connect and disconnect wiring from the terminal. Quick-disconnect power cords allow you to add a NEMA plug to these fans, so you can connect them to a standard outlet.

Wire Lead Connection—Install fans with wire leads directly to your power source—there’s no need for additional connectors.

IP55 Enclosure Rating—IP55-rated fans can also stand up to washdowns from low-pressure jets of water.

Hazardous Location Equipment-Cooling Fan Kits

Cool electronics and other sensitive equipment in potentially unsafe areas. These fans are non-sparking, so they’re safe for use around gas and explosive dust. They also withstand washdowns, occasional submersion in water, and wet weather. They’re not for use in mines. Ball bearings reduce the heat that’s generated to prolong fan lifespan.

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.
