ABSTRACT:
A filter cartridge assembly is formed of a series of stacked disc members interlocking with one another and held in compression by a preload force exerted through respective end members at opposite ends of the assembly. Each of the disc members is provided with a series of raised surfaces -- bosses, for positioning filter media thereon and providing fluid flow paths for the filtrate to pass through openings in the disc members into a central passage and out of the cartridge. Cooperating raised edge surfaces adjacent to the outer and inner periphery, engage and seal the filter media under a compressive load along the surfaces adjacent the outer and inner edges of the media, when the respective disc members are in stacked relationship and the media is sandwiched between neighboring discs.
