Abstract

A liquid filter having a quick-disconnect filter element mount includes a filter vessel having an inlet nozzle and an outlet nozzle. The vessel has a tube sheet which spans across at least a part of the vessel and defines an influent chamber in communication with the inlet nozzle and a filtrate chamber in communication with the outlet nozzle. A plurality of support core elements are connected to the tube sheet at a fixed end. A free end of the core elements extends into the influent chamber and includes a retaining barrel mounted to the free end. Filter elements, such as cartridge type elements which have a central opening therein are positioned on the core elements, against the tube sheet. The quick disconnect mount includes a post having a retaining body adapted to be releasably connected to the retaining barrel in the support core, to retain the filter element in place on the support core, in engagement with the tube sheet. The quick-disconnect mount includes a spring element and at least one tensioning element to provide a predetermined, settable pre-load compression on the filter element when the mount is positioned with the filter element in place on the support core. The quick-disconnect can be configured for use with up-flow and down-flow type filter vessels and is configured to readily permit removal and replacement of the filter elements.
