HOFFMAN HG0400404 Exhaust Grill/Filter

The HOFFMAN HG0400404 is a plastic exhaust grill and filter designed for electrical control enclosures. It carries a NEMA Type 12 rating and features a matte finish with a silicone gasket. The unit measures 4.42 inches high by 4.44 inches long with a 1.6 inch width.

Suited for NEMA 12 enclosure ventilation

This accessory suits technicians maintaining Type 12 enclosures who need straightforward filter replacement. It is not intended for enclosures requiring different NEMA ratings or for installations where plastic construction and the specified dimensions are unsuitable.

Questions about this item

What size cut-out does the 4.42" H x 4.44" L exhaust grill require in my NEMA 12 enclosure?

The grill is designed for a NEMA Type 12 enclosure with a 4.42" high by 4.44" long opening, using the included silicone gasket to seal the 1.6" deep frame against the panel.

Can I install this filter on an older Hoffman enclosure that uses a different latching system?

This exhaust grill is built for easy filter replacement on compatible NEMA 12 enclosures; verify your existing cabinet has the matching 4.42" x 4.44" cut-out and mounting pattern before fitting.

How do I confirm the silicone gasket is sealing properly after mounting the grill?

After securing the grill, inspect the perimeter — the 1.6" deep frame should sit flush with the enclosure wall and the silicone gasket must show even compression all around with no visible gaps.
