  • Publication number: 20210086115
    Abstract: A filter cartridge endplate (12) is described herein that has a integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (12), where a separator (10) is built into the endplate (12) the separates fluid flow. The endplate (12) includes a plate with a major surface, a separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) ae configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate (12).
