Abstract

A panel filter including a generally rectangular border frame having four sides; a filter media supported by the border frame and extending within the border frame; and a key formed into the border frame is provided. The key is used to properly determine if the filter is appropriate for mounting in a housing. It may also be used for properly orienting the filter within the housing. A system including the housing is also provided. Methods of providing biosecurity for animal confinements are also provided.

Claims

1. A panel filter comprising:

a generally rectangular border frame having four sides;

a filter media supported by the border frame and extending within the border frame;

a key formed into the border frame, the key comprises a first recessed corner formed at a juncture between a first pair of the sides; and

wherein at least one juncture between a different pair of sides than said first pair is a non-recessed corner, and wherein the generally rectangular border is square, wherein the combination of the recessed corner and the non-recessed corner provides orientation means for orienting the panel filter to provide a predetermined orientation for the filter media when in use.

2. The panel filter of claim 1, further comprising a generally rectangular gasket sealing against the border frame, the key also being at least partially formed into the rectangular gasket.

3. The panel filter of claim 1, wherein the rectangular border frame includes an outer periphery including a front face, a back face and an outer peripheral surface connecting the front and back faces, the outer peripheral surface defines an outermost perimeter, wherein the key is formed along the outer peripheral surface and extends between the front face and the back face.

4. The panel filter of claim 1, wherein a second key is formed along the border frame by a second recessed corner formed at a juncture between a pair of the sides, the second recessed corner being located kitty corner to the first recessed corner.

5. The panel filter of claim 1, wherein the rectangular border frame includes an outer periphery including a front face, a back face and an outer peripheral surface connecting the front and back faces, the outer peripheral surface defines an outermost perimeter, wherein the first recessed corner comprises a chamfer defining part of the outer peripheral surface.

6. The panel filter of claim 5, wherein the chamfer is flat.

7. The panel filter of claim 1, wherein the filter media comprises a pleated filter media panel extending laterally between the sides of the border frame.

8. The panel filter of claim 7, wherein the rectangular border frame includes an outer periphery including a front face, a back face, an outer peripheral surface connecting the front and back faces along an outer periphery of the border frame and an inner peripheral surface connecting the front and back faces along an inner periphery of the border frame, the pleated filter media panel being sealingly connected to the inner peripheral surface and generally confined between the front and back faces.

9. The panel filter of claim 8, wherein the border frame comprises a generally rectangular header defining an outermost perimeter and a generally rectangular extension wall depending from the header and defining a smaller perimeter than the outermost perimeter to provide a step in the outer periphery at the transition from the header to the extension wall.

10. The panel filter of claim 1, wherein the panel filter is a V-Bank filter, the filter media comprising a plurality of separate filter media elements, with pairs of separate filter media elements forming a V-shaped configuration.

11. A filter assembly comprising:

a panel filter comprising;

a generally rectangular border frame having four sides;

a filter media supported by the border frame and extending within the border frame;

a key formed into the border frame;

a housing comprising a mounting frame, the mounting frame including a seating recess, the rectangular border frame being seated on the seating recess with a generally rectangular gasket therebetween;

a housing key formed along the seating recess mating with said key of the panel filter.

12. The filter assembly of claim 11, wherein the housing key comprises a male projection projecting laterally and the key of the panel filter comprises a female key receiving the housing key, wherein the female key must be present to allow installation of the panel filter into the housing.

13. The filter assembly of claim 11, wherein said mounting frame includes a plurality of square openings, each receiving a separation one of said panel filter, each square opening having a seating recess and a housing key, the housing keys being located in the same corner of each of the square openings, wherein the filter media comprises a pleated filter media panel extending laterally between the sides of the border frame, with pleat flanks oriented in a predetermined direction, wherein the key of each panel filter is arranged in predetermined orientation relative to the pleat flanks such that when each panel filter is mounted into the housing, the pleat flanks of each panel filter are all aligned and oriented in a common direction due to mating of the keys and housing keys.

14. A method of providing bio-security for an animal confinement building comprising:

inserting a primary filter into a housing attached to a confinement building, the housing being attached proximate an opening into an area of the confinement building where animals are kept, the primary filter being a panel filter comprising;

a generally rectangular border frame having four sides;

a filter media supported by the border frame and extending within the border frame;

a key formed into the border frame;

the housing comprising a mounting frame, the mounting frame including a seating recess, the rectangular border frame being seated on the seating recess with a generally rectangular gasket therebetween;

a housing key formed along the seating recess mating with said key of the panel filter.

15. The method of claim 14, further comprising attaching the housing to the confinement building.

16. The method of claim 14, wherein the filter media is a MERV 16 filter media.

17. The method of claim 14, wherein the step of inserting the primary filter into the housing includes sealing the primary filter to the housing including axially compressing the rectangular gasket.

18. The method of claim 14, wherein the step of inserting includes mating the housing key and the filter key such that pleats of the filter media are aligned in a vertical orientation rather than a horizontal orientation.
