Abstract

An air filtration system is coupled to an inlet of an enclosure of or to a piece of equipment. The air filtration system is coupled to the enclosure at the air inlet such that air entering the enclosure through the air inlet passes through the air filtration system. The air filtration system includes a frame assembly. The frame assembly includes an outer frame and a support mesh. The outer frame is coupled to the enclosure. The air filtration system includes a door assembly. The door assembly includes a door frame and a door support mesh. The door assembly is received by and mechanically coupled to the frame assembly. The air filtration system includes filter media positioned in an interior of the air filtration system defined by the frame assembly and the door assembly.

First claim

The invention claimed is:

1. A power generator trailer, the power generator trailer including:
an enclosure, the enclosure including at least one air inlet;
a diesel engine positioned within the enclosure; and
an air filtration system, the air filtration system coupled to the enclosure at the air inlet such that air entering the enclosure through the air inlet passes through the air filtration system, the air filtration system including:
a frame assembly, the frame assembly including an outer frame and a support mesh, the outer frame coupled to the enclosure;
a door assembly, the door assembly including a door frame and a door support mesh, the door assembly received by and mechanically coupled to the frame assembly;
filter media positioned in an interior of the air filtration system defined by the frame assembly and the door assembly, and
a door retention assembly, the door retention assembly positioned to couple the door assembly to the frame assembly, the door retention assembly comprising a retention screw threadedly coupled to the frame assembly and passing through a slot or hole formed in the door frame, wherein the door frame comprises a retention bracket, the retention bracket being U-shaped, the retention bracket including an outer retention hole and an inner retention hole, the retention screw passing through the outer and inner retention holes.

2. The power generator trailer of claim 1 , wherein the support mesh of the frame assembly further comprises one or more support pins, the support pins engaging the filter media.

3. The power generator trailer of claim 1 , wherein the outer frame of the frame assembly further comprises a mounting flange, the frame assembly coupled to the enclosure by the mounting flange.

4. The power generator trailer of claim 1 , wherein the frame assembly further comprises a lower retaining bracket, the lower retaining bracket positioned to retain the door assembly to the frame assembly.

5. The power generator trailer of claim 1 , wherein the door retention assembly further comprises a retention feature adapted to retain the retention screw to the retention bracket.

6. The power generator trailer of claim 5 , wherein the retention feature comprises jam nuts.

7. An air filtration system comprising:
a frame assembly, the frame assembly including an outer frame and a support mesh;
a door assembly, the door assembly including a door frame and a door support mesh, the door assembly received by and mechanically coupled to the frame assembly;
filter media positioned in an interior of the air filtration system defined by the frame assembly and the door assembly, and
a door retention assembly, the door retention assembly positioned to couple the door assembly to the frame assembly, the door retention assembly comprising a retention screw threadedly coupled to the frame assembly and passing through a slot or hole formed in the door frame, wherein the door frame comprises a retention bracket, the retention bracket being U-shaped, the retention bracket including an outer retention hole and an inner retention hole, the retention screw passing through the outer and inner retention holes.

8. The air filtration system of claim 7 , wherein the support mesh of the frame assembly further comprises one or more support pins, the support pins engaging the filter media.

9. The air filtration system of claim 7 , wherein the outer frame of the frame assembly further comprises a mounting flange adapted to allow the air filtration system to be mechanically coupled to a piece of equipment.

10. The air filtration system of claim 7 , wherein the frame assembly further comprises a lower retaining bracket, the lower retaining bracket positioned to retain the door assembly to the frame assembly.

11. The air filtration system of claim 7 , wherein the door retention assembly further comprises a retention feature adapted to retain the retention screw to the retention bracket.

12. The air filtration system of claim 11 , wherein the retention feature comprises jam nuts.
