Height adjustable center tube and guide for a filter cartridge assembly

摘要

A filter media includes a media pack having a central opening that extends between opposing ends of the media pack. A support member, such as a center tube, extends through the central opening and supports one of the opposing ends. A second support member, such as a filter cartridge assembly guide, is secured to the second support member and supports the other of the opposing ends. In one example, the center tube includes a seat that extends radially outwardly from an axially body of the center tube to support the media pack. The first and second support members are secured by an interlocking connection of any suitable configuration. The disclosed arrangement can be used to reduce the number of components required for providing a large number of filter cartridge assembly. Each of a plurality of media packs provide different heights. A first support member is selected to support one of the opposing ends. A second support member is selected to accommodate the height of the selected media pack. The first and second support members cooperate with one another to support the opposing ends of the media pack.
