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.

Hazardous Location Equipment-Cooling Fans

Safely cool electronics and equipment where explosive gases could be present due to equipment failure. ATEX certified, these fans meet European standards for hazardous locations. They’re also IP rated, so they seal out dust and are protected from water if briefly submersed. All have ball bearings that decrease noise for quiet operation. Their bearings reduce heat as they run as well, extending their life.
