Introducing Dust-Tight Enclosures from Hoffman

Hoffman NEMA Type 9 Enclosures

Hoffman’s NEMA Type 9 enclosures are specifically designed to meet the rigors of hazardous environments where combustible dust may be present. This unique design makes the NEMA Type 9 enclosures ideal for applications like grain elevator systems, mining process controls, and drill rig systems.

NEMA Type 9 Wall Mount Enclosure Features

  • 19 inch (5 mm), 0.25 inch (6 mm) and 0.38 inch (10 mm) steel plate
  • Covers are 0.25 inches (6 mm) thick to allow mounting of NEMA 9 pushbuttons and pilot lights, which require threaded holes
  • Heavy duty cover hinges when the height (“A”) of the enclosure is 20.00 inches (508 mm) or more
  • Fiber gasket to insure dust-tight closure (mechanically attached to cover)
  • Weldnuts or collar studs provided for mounting optional panel
  • ANSI 61 gray polyester powder finish inside and out over pretreated surfaces.

In addition to NEMA Type 9 wall mount enclosures, Hoffman offers a full line of enclosures and purging/pressurization systems for hazardous locations. Not only does Hoffman provide standard catalog items but they also allow customization to meet each unique application.
