Abstract
A filter assembly employs a base which mounts a disposable filter element cartridge. The cartridge includes either a single stage or a dual stage filter system. The base has custom and generic structural members. Variations in base design are accommodated in the custom member, the generic member having a generic design. The custom member is molded from polymeric material and requires no additional machining or treatment prior to use. This eliminates filter model specific shop fixtures and gigs, reducing costs and providing greater flexibility.
