Abstract

A V-bank filter including a first pleated panel and a second pleated panel. The first pleated panel and the second pleated panel are both formed from a single, continuous web of pleated filter material into a V-configuration and the pleats of the first panel are interleaved with the pleats of the second panel at an apex of the V-configuration.

First claim

What is claimed is:

1 . A V-bank filter comprising:
a first pleated panel and a second pleated panel; the first pleated panel and the second pleated panel are both formed from a single, continuous web of pleated filter material into a V-configuration, and wherein the pleats of the first panel are interleaved with the pleats of the second panel at an apex of the V-configuration.

2 . The V-bank filter of claim 1 wherein a plurality of crowns of the first pleated panel are partially disposed within a plurality of valleys of the second pleated panel at the apex.

3 . The V-bank filter of claim 2 comprising a first side panel joining the first pleated panel to the second pleated panel on a first side and a second side panel joining the first pleated panel to the second pleated panel on a second side.

4 . The V-bank filter of claim 3 comprising a frame surrounding an open end of the V-configuration.

5 . The V-bank filter of claim 1 comprising:
the first pleated panel, the second pleated panel, a third pleated panel and a fourth pleated panel all formed from a single, continuous web of pleated filter material into a first V-configuration and a second V-configuration; and
wherein the pleats of the first panel are interleaved with the pleats of the second panel at an apex of the first V-configuration, the pleats of the second panel are interleaved with the pleats of the third panel adjacent an open end of the first V-configuration and the pleats of the third panel are interleaved with the pleats of the fourth panel at an apex of the second V-configuration.

6 . The V-bank filter of claim 5 wherein a plurality of crowns of the first pleated panel are partially disposed within a plurality of valleys of the second pleated panel at the apex of the first V-configuration and a plurality of crowns of the third pleated panel are partially disposed within a plurality of valleys of the fourth pleated panel at the apex of the second V-configuration.

7 . The V-bank filter of claim 6 comprising a first side panel joining the first pleated panel, the second pleated panel, the third pleated panel, and the fourth pleated panel on a first side; and a second side panel joining the first pleated panel, the second pleated panel, the third pleated panel, and the fourth pleated panel on a second side.

8 . The V-bank filter of claim 7 comprising a frame surrounding the first and the second V-configurations.

9 . The V-bank filter of claim 1 wherein an end cap is not adhered to the apex and the apex remains permeable to air.

10 . A V-bank filter comprising:
a first pleated panel and a second pleated panel formed into a V-configuration having an open end and an apex; the folds of the first pleated panel and the folds of the second pleated panel both extending in a longitudinal direction from the open end to the apex; and wherein the first pleated panel and the second pleated panel are both formed from a single, continuous web of pleated filter material.

11 . The V-bank filter of claim 10 wherein the pleats of the first panel are interleaved with the pleats of the second panel at the apex.

12 . The V-bank filter of claim 11 wherein a plurality of crowns of the first pleated panel are partially disposed within a plurality of valleys of the second pleated panel at the apex.

13 . The V-bank filter of claim 12 comprising a first side panel joining the first pleated panel to the second pleated panel on a first side and a second side panel joining the first pleated panel to the second pleated panel on a second side.

14 . The V-bank filter of claim 13 comprising a frame surrounding the open end.

15 . The V-bank filter of claim 10 comprising:
the first pleated panel and the second pleated panel formed into a first V-configuration having an open end and an apex;
a third pleated panel and a fourth pleated panel formed into a second V-configuration having an open end and an apex;
the folds of the first pleated panel and the folds of the second pleated panel extending in a longitudinal direction from the open end to the apex of the first V-configuration;
the folds of the third pleated panel and the folds of the fourth pleated panel extending in a longitudinal direction from the open end to the apex of the second V-configuration; and
wherein the first pleated panel, the second pleated panel, the third pleated panel, and the fourth pleated panel are all formed from a single, continuous web of pleated filter material.

16 . The V-bank filter of claim 15 wherein the pleats of the first panel are interleaved with the pleats of the second panel at the apex of the first V-configuration, and the pleats of the third panel are interleaved with the pleats of the fourth panel at the apex of the second V-configuration.

17 . The V-bank filter of claim 16 wherein a plurality of crowns of the first pleated panel are partially disposed within a plurality of valleys of the second pleated panel at the apex of the first V-configuration, and a plurality of crowns of the third pleated panel are partially disposed within a plurality of valleys of the fourth pleated panel at the apex of the second V-configuration.

18 . The V-bank filter of claim 17 comprising a first side panel joining the first pleated panel, the second pleated panel, the third pleated panel and the fourth pleated panel on a first side; and a second side panel joining the first pleated panel, the second pleated panel, the third pleated panel and the fourth pleated panel on a second side.

19 . The V-bank filter of claim 18 comprising a frame surrounding the open ends of the first and the second V-configurations.

20 . A method of making a V-bank filter comprising:
folding a filter media to form a primary fold joining a first panel and a second panel; pleating the filter media transversely along the primary fold to form a first pleated panel joined to a second pleated panel by a pleated primary fold; and separating the first pleated panel from the second pleated panel into a V-configuration to form the V-bank filter.

21 . The method of claim 1 comprising attaching a first side panel to a first side of V-configuration and attaching a second side panel to a second side of the V-configuration.

22 . The method of claim 21 comprising disposing the V-bank filter into a frame.

23 . A method of making a V-bank filter comprising:
pleating a filter media to form three primary folds joining a first panel, a second panel, a third panel, and a fourth panel; pleating the filter media transversely along the three primary folds to form a first pleated panel joined to a second pleated panel, a third pleated panel joined to the second pleated panel, and a fourth pleated panel joined to the third pleated panel by three pleated primary folds; separating the first pleated panel from the second pleated panel into a first V-configuration; and separating the third pleated panel from the fourth pleated paned into a second V-configuration to form the V-bank filter.

24 . The method of claim 23 comprising attaching a first side panel to a first side of the first and second V-configurations and attaching a second side panel to a second side of the first and second V-configurations.

25 . The method of claim 24 comprising disposing the V-bank filter into a frame.
