Abstract

A method of manufacturing a media assembly comprises winding a filter media about a center axis into a media roll and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies. The media roll is cut along at least one plane that is parallel to the center axis.

First claim

What is claimed is:

1 . A method of manufacturing a media assembly, the method comprising:
winding a filter media about a center axis into a media roll; and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies, the media roll being cut along at least one plane that is parallel to the center axis.

2 . The method of claim 1 , further comprising securing a side panel to one of two cut ends of one of the at least two media packs.

3 . The method of claim 1 , further comprising installing the at least two media packs into a frame.

4 . The method of claim 1 , further comprising potting the at least two media packs so as to form a seal member on at least one cut side of the at least two media packs.

5 . The method of claim 1 , further comprising attaching the media assembly to a second media assembly so as to form an S-shape.

6 . The method of claim 1 , wherein the media roll is cut such that the at least two cut lines align with each other and extend through the center axis so as to produce at least two identical media packs.

7 . The method of claim 1 , where in the media roll is cut using a laser.

8 . A media assembly comprising:
a media pack comprising a plurality of layers of filter media, the media pack defining an inlet flow face, an outlet flow face, a first side wall, a second side wall, a radially inner edge, and a radially outer edge, the first side wall and the second side wall each extending axially between the inlet flow face and the outlet flow face and radially between the radially inner edge and the radially outer edge; a first side panel positioned along and forming a seal with the first side wall such that fluid entering through the inlet flow face cannot exit the media pack through the first side wall; and a second side panel positioned along and forming a seal with the second side wall such that fluid entering through the inlet flow face cannot exit the media pack through the second side wall, the media pack being formed by winding the filter media around a center axis into a media roll and cutting the media roll along at least two cut lines to form the first side wall and the second side wall.

9 . The media assembly of claim 8 , wherein the plurality of layers of filter media curve about the center axis and form an arc shape.

10 . The media assembly of claim 8 , wherein the plurality of layers of filter media comprise an innermost layer and an outermost layer that is longer than the innermost layer, the innermost layer defining an inner edge of the media pack, and the outermost layer defining an outer edge of the media pack.

11 . The media assembly of claim 8 , wherein the plurality of layers of filter media comprise an innermost layer and an outermost layer that has substantially the same axial length and curvature as the innermost layer, the innermost layer defining an inner edge of the media pack, and the outermost layer defining an outer edge of the media pack.

12 . The media assembly of claim 8 , further comprising a center support, the center support extending axially on the media roll and configured to support the media roll.

13 . The media assembly of claim 12 , where in the media pack is positioned proximate to a second media pack such that the radially inner edge of the media pack is attached to a radially outer edge of the second media pack.

14 . The media assembly of claim 12 , wherein the plurality of layers of filter media are radially spaced further away from each other after the media pack has been cut so as to increase a radial thickness of the media pack.

15 . The media assembly of claim 12 , wherein the media roll formed is square with rounded corners such that a plurality of identical media packs are formed when the media roll is cut.

16 . A filter element comprising:
a media assembly comprising
a media pack comprising a plurality of layers of filter media, the media pack defining an inlet flow face, an outlet flow face, a first side wall, a second side wall, a radially inner edge, and a radially outer edge, the first side wall and the second side wall each extending axially between the inlet flow face and the outlet flow face and radially between the radially inner edge and the radially outer edge,
a first side panel positioned along and forming a seal with the first side wall such that fluid entering through the inlet flow face cannot exit the media pack through the first side wall, and
a second side panel positioned along and forming a seal with the second side wall such that fluid entering through the inlet flow face cannot exit the media pack through the second side wall,
the media pack being formed by winding the filter media around a center axis into a media roll and cutting the media roll along at least two cut lines to form the first side wall and the second side wall.

17 . The filter element of claim 16 wherein the media assembly further comprises a center support positioned along the radially inner edge between the first side wall and the second sidewall, the center support extending axially between the inlet flow face and the outlet flow face.

18 . The filter element of claim 16 , wherein the plurality of layers of filter media comprise an innermost layer and an outermost layer that is longer than the innermost layer, the innermost layer defining an inner edge of the media pack, and the outermost layer defining an outer edge of the media pack.

19 . The filter element of claim 16 , wherein:
the first side panel is positioned such that the first side panel extends axially along an entire length of the first side wall; and the second side panel is positioned such that the second side panel extends axially along an entire length of the second side wall.

20 . The filter element of claim 16 , wherein the formed media roll comprises a circular ring segment.
