Hazardous Location Upblast Roof-Mount Exhaust Fans

With a UL-listed motor, these fans can be used in hazardous environments with combustible gases and dust to draw stagnant and humid air out through your roof, forcing it up and away from its surface.

Direct Drive

High-Flow Low-Pressure Hazardous Location Compressed Air Blowers

Safely produce high-flow compressed air with low pressure or vacuum in environments with flammable gases and combustible dust, such as propane and carbon-based dust. These blowers have an explosion-proof motor and are UL listed for use in hazardous locations. Also known as regenerative blowers, they are commonly used to operate pump drives, lift tables, and conveying systems. They can also be used for drying, exhausting, and aerating.
