Abstract
A filter element includes a frame having an outlet panel and two side panels defining a U-shape. A U-shaped media anchor channel extends along the distal side edge of each panel. Each media anchor channel can have a snap-tab or other locking feature. The element encloses a pleated panel filter media pack having a side edge along each side of the pack. Each side edge of the media pack is located in a media anchor channel, and a bead of adhesive is applied along the channel. A pair of seal bars, each having a u-shape and a snap-tab or other feature that cooperates with the u-shape and the snap-tab of each media anchor channel, is pressed into each channel. Each seal bar mechanically retains a respective media side edge in the channel and together with the adhesive, provides a consistent, robust seal between the media and the frame.
Claims22
A filter element, comprising:
- a. a frame having an outlet panel and two side panels along opposite sides of the outlet panel, the side panels each having a U-shaped media anchor channel along a distal side edge of the respective side panel;
- b. filter media pack supported within the frame, the filter media pack including side edges along opposite sides of the media, each media side edge being at least partially received within a respective media anchor channel;
- c. a bead of adhesive along each media anchor channel for adhesively sealing the respective media side edge within the media anchor channel;
- and,
- d. two seal bars, each seal bar having a geometry that cooperates with a respective media anchor channel to mechanically retain the respective media side edge in the respective media anchor channel.
A filter element, comprising:
- a. a frame having a pair of side panels, at least one of the side panels having a media anchor channel along a distal side edge of the one side panel;
- b. filter media supported within the frame, the filter media including side edges along opposite sides of the media, one of the media side edges being at least partially received within the media anchor channel;
- c. adhesive means along the media anchor channel for adhesively sealing the media side edge within the media anchor channel;
- and,
- d. a seal bar having a configuration that cooperates with the media anchor channel to mechanically retain the media side edge in the media anchor channel.
A method of assembling a filter element having a frame with an outlet panel and two side panels along opposite sides of the outlet panel, the side panels each having a U-shaped media anchor channel along a distal side edge of the respective side panel;
- a filter media pack including side edges along opposite sides of the filter media pack;
- and two seal bars, each seal bar having a geometry that can mechanically inter-engage with a geometry of a respective media anchor channel, comprising the steps of:
- a. locating the filter media pack in the frame and against the outlet panel, with the side panels of the frame along opposite side of the filter media pack, and such that the side edges of the filter media pack are each received within a respective media anchor channel;
- b. depositing a bead of adhesive along each media anchor channel;
- and
- c. locating each seal bar within a respective media anchor channel to mechanically retain the respective media side edge within the respective media anchor channel.
