Abstract: A filter assembly is described herein for controlling the air passing therethrough. The filter assembly can include a housing comprising a cavity formed therein. The filter assembly can also include a filter positioned within the cavity and coupled to the housing.

Abstract: A manifold within an explosion-proof enclosure is described herein. The manifold can include an inlet duct coupled to an air moving device, where the inlet duct can receive exhaust air from the air moving device. The manifold can further include an outlet duct that includes a perimeter and at least one channel, where the outlet duct can send the exhaust air outside the explosion-proof enclosure, where the perimeter of the outlet duct is coupled to a first portion of an inner surface of an outer wall of the explosion-proof enclosure, and where the first portion of the inner surface includes at least one aperture that traverses the outer wall. The manifold can also include a body that includes a cavity, where the body couples the inlet duct to the at least one channel, and where the exhaust air flows from the inlet duct through the cavity to the outlet duct.
