Features and Benefits

Explosion-Proof Power Switches

UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points.

Explosion-Proof Potted Fittings

Conduit is filled with an expanding cement mixture to isolate explosion-proof components from potential sources of ignition; explosion-proof fittings meet requirements of NEC for Class I, Division 1 hazardous locations.

Pre-Filter Grounding Clip

A grounding wire connects the body of the Explosion-Proof FFU to a metal wireframe embedded in the pre-filter as a safeguard against sparking.

Non-Sparking Direct-Drive Motor

Explosion-proof motors use a non-sparking polypropylene fan and cast-iron brackets attached to the heavy duty rolled steel frame

Explosion-Proof Junction Box

The reinforced junction box of the explosion-proof fan filter unit is built to withstand and contain an explosive reaction within the conduit system.
