Patent number: 11958007Abstract: 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.Type: GrantFiled: March 2, 2023Date of Patent: April 16, 2024Assignee: Parker-Hannifin CorporationInventor: Timothy L.
