Abstract
Filter elements and methods of manufacturing filter elements are provided. Examples of filter elements include a media pack and a frame attached thereto. In one example, the frame includes a side panel that is or includes a foldable portion. The foldable portion is folded away from the media pack and an adhesive is located therebetween during assembly. In other examples, a media support member is provided that includes at least one side support panel that supports a side of the media pack. A portion of the side support member is positioned between adjacent pleat panels of the media pack.
Claims25
A filter element comprising:
- a media pack;
- a frame including at least one side panel extending along a side of the media pack, the side panel having a foldable portion enabling the side panel to be folded relative to the media pack;
- a mass of adhesive between the foldable portion of the side panel and the media pack, fixing the frame to the media pack;
- wherein:
- the media pack has a plurality of pleat panels, pairs of adjacent ones of the plurality of pleat panels being interconnected by a fold;
- a media support member having a first side support panel having a first portion interposed between first and second pleat panels of a first pair of adjacent pleat panels;
- the adhesive being interposed between the first pleat panel and the frame with the adhesive directly contacting the frame and directly contacting the first pleat panel.

A method of assembling a filter element including a frame, a media pack, and a media support member, the media support member includes at least one side panel positioned adjacent the side of the media pack, wherein the frame includes at least one side flap extending along a side of the media pack, comprising the steps of:
- i. folding a foldable portion of the at least one side flap away from the media pack;
- ii. applying a bead of adhesive between the foldable portion of the side flap and the media pack;
- iii. folding the foldable portion of the side flap back towards the media pack, capturing the adhesive between the side flap and the media pack;
- iv. curing the adhesive;
- the method further comprising:
- i. folding a portion of the media pack to form first and second pleat panels;
- ii. positioning the side panel of the media support member adjacent the side of the media pack such that a portion of the side panel is positioned between the first and second pleat panels;
- iii. positioning the media pack within the frame with frame extending over the first pleat panel such that the first pleat panel is located between the frame and the side panel of the media support member;
- and
- iv. applying the bead of adhesive between the frame and the first pleat panel of the media pack such that the adhesive directly contacts an inner surface of frame and an outer surface of the first pleat panel.
