Abstract

A portable air filtration system used in industrial environments to filter and re-circulate fumes from a fume source includes a housing that filters the fumes from the fume source. The housing defines at least one housing inlet to receive the fumes and a housing outlet to dispense the fumes. A receiving assembly is releaseably engageable with the at least one housing inlet and includes a receiver inlet and a receiver outlet. The receiver outlet is in fluid communication with the at least one housing inlet. The receiver inlet receives the fumes from the fume source and transfers the fumes to the housing inlet. The system is capable of being modified between a plurality of configurations.

Claims

1. A portable air filtration system for use in industrial environments to filter and re-circulate fumes from a fume source comprising:

a housing for filtering the fumes from the fume source, said housing defining at least one housing inlet for receiving the fumes and a housing outlet for dispensing the fumes; and

a receiving assembly being releaseably engageable to said at least one housing inlet and having a receiver outlet in fluid communication with said at least one housing inlet and presenting a face defining a receiver inlet for receiving the fumes from the fume source;

wherein said system is capable of being modified between a plurality of configurations.

2. The system as set forth in claim 1 wherein said housing includes a plurality of housing inlets for receiving the fumes from the fume source and wherein said receiving assembly is releaseably engageable with any one of said plurality of housing inlets.

3. The system as set forth in claim 2 further including a housing plate being releaseably engageable with any one of said plurality of housing inlets for blocking the flow of fumes into said housing through any one of said plurality of housing inlets having said housing plate engaged therewith.

4. The system as set forth in claim 3 wherein said receiving assembly is releaseably engageable with any one of said plurality of housing inlets and said housing plate is releaseably engageable with any other of said plurality of said housing inlets.

5. The system as set forth in claim 1 further including at least one wheel secured to said housing for moving said housing.

6. The system as set forth in claim 5 further including a plurality of wheels, each of said wheels being disposed adjacent a corner of said housing.

7. The system as set forth in claim 1 wherein said at least one housing inlet is disposed on a front face of said housing.

8. The system as set forth in claim 1 wherein said at least one housing inlet is disposed on a top face of said housing.

9. The system as set forth in claim 1 further including a plurality of said housing inlets.

10. The system as set forth in claim 9 wherein at least one of said plurality of housing inlets is disposed on a front face of said housing and at least one of said plurality of housing inlets is disposed on a top face of said housing.

11. The system as set forth in claim 1 further including a fan disposed in said housing and operatively connected to a motor for generating suction at said at least one housing inlet and for propelling the fumes out of said housing through said housing outlet.

12. The system as set forth in claim 1 further including a filter disposed in at least one of said housing and said receiving assembly for removing particulates from the fumes.

13. The assembly as set forth in claim 1 further including a plurality of louvers extending across said receiver inlet for dispersing the fumes entering said receiving assembly from the fume source and for filtering out large materials from the fumes.

14. The system as set forth in claim 1 wherein said receiving assembly is at least one duct arm having a first end in fluid communication with said at least one housing inlet of said housing and extending to a distal end for conveying fumes to said at least one housing inlet.

15. The assembly as set forth in claim 14 wherein said duct arm includes at least one flexible section and at least one rigid tube.

16. The assembly as set forth in claim 15 wherein each of said at least one flexible sections is defined by a bellows tube.

17. The assembly as set forth in claim 15 wherein said duct arm serially includes a first flexible section and a first rigid tube and a second flexible section and a second rigid tube and a third flexible section.

18. The assembly as set forth in claim 14 further including a first swivel interconnecting said at least one housing inlet of said housing and said first end of said duct arm for allowing rotation of said duct arm relative to said housing.

19. The system as set forth in claim 18 further including a duct plate being releaseably engageable to said at least one housing inlet and defining said first swivel for interconnecting said at least one housing inlet of said housing and said first end of said duct arm.

20. The system as set forth in claim 14 further including a hood having a hood outlet in fluid communication with said distal end of said duct arm and presenting a face defining a hood inlet for receiving the fumes from the fume source.

21. The assembly as set forth in claim 20 further comprising a second swivel interconnecting said hood outlet of said hood and said distal end of said duct arm for allowing rotation of said hood relative to said duct arm.

22. The system as set forth in claim 14 further including a plurality of duct arms in fluid communication with said at least one housing inlet of said housing for conveying fumes to said at least one housing inlet.

23. The system as set forth in claim 1 wherein said receiver assembly is an intake plenum having a plenum outlet in fluid communication with said at least one housing inlet and presenting a face defining plenum inlet for receiving the fumes for the fume source.

24. The system as set forth in claim 23 wherein said plenum inlet faces upwardly to create a downdraft flow into said housing.

25. The system as set forth in claim 24 wherein said at least one housing inlet is disposed on a front face of said housing.

26. The system as set forth in claim 24 further including at least one support leg extending downwardly from said intake plenum for supporting said intake plenum.

27. The system as set forth in claim 23 wherein said plenum inlet faces outwardly to create a backdraft flow into said housing.

28. The system as set forth in claim 27 wherein said at least one housing inlet is disposed on a top face of said housing.
