1. A manifold within an explosion-proof enclosure, the manifold comprising:

  • a housing having a first end and a second end, wherein the second end abuts against an inner surface of an outer wall of the explosion-proof enclosure;

    an inlet duct coupled to an air moving device and disposed within the first end of the housing, wherein the inlet duct is configured to receive exhaust air from the air moving device;

    an outlet duct comprising a first perimeter and at least one channel, wherein the outlet duct is disposed within the second end of the housing, wherein the outlet duct is configured to send the exhaust air outside the explosion-proof enclosure, wherein the first perimeter of the outlet duct is coupled to a first portion of the inner surface of the outer wall of the explosion-proof enclosure, wherein the first portion of the inner surface comprises at least one aperture that traverses the outer wall;

    a body comprising a cavity and disposed within the housing between the first end and the second end of the housing, wherein the body couples the inlet duct to the at least one channel, and wherein the exhaust air flows from the inlet duct through the cavity to the outlet duct; and

    a bracket that abuts against and overlaps an outer surface of the outlet duct adjacent to the first perimeter of the outlet duct to secure the outlet duct to the explosion-proof enclosure, wherein the bracket is coupled to a second portion of the inner surface of the outer wall of the explosion-proof enclosure, wherein the second portion encompasses the first portion,wherein the explosion-proof enclosure, when the bracket abuts against and overlaps the outer surface of the outlet duct, and when the bracket abuts against and is coupled to the inner surface of the outer wall of the explosion-proof enclosure, meets applicable industry standards for the explosion-proof enclosure.
