Title:
RECYCLABLE FILTER CARTRIDGE AND PRESSURE VESSEL
Document Type and Number:
WIPO Patent Application WO2001026772
Kind Code:
B1
Abstract:
A filter assembly (20) is described that includes a substantially recyclable filter cartridge (30) inside a pressure vessel (22). The invented filter cartridge comprises substantially non-pressure bearing walls, except for a pressure-bearing neck (44) that is adapted to withstand high pressures preferably in the range of about 500 psi (34, 47. 10<5> Pa) from the inside. The walls of the filter cartridge that are incapable of withstanding significant internal pressure are surronded on the outside by a pressure vessel (22). The invented cartridge need not seal ot the pressure vessel, because the cartridge neck (44) protrudes outside of the pressure vessel (22) to seal directly to a filter head. The cartridge preferably includes a quick-disassembly mechanism for allowing quick and non-destructive access to the internal components and media of the cartridge.
