ABSTRACT:
A filter apparatus for use in filtering a fluid is provided. The filter apparatus has a plug-in, quick-connect cartridge. The filter apparatus has walls forming a first chamber and a second chamber. The filter apparatus also has a diaphragm having a first surface and having a second surface for separating the chambers. The diaphragm has an aperture with an inner surface for receiving the cartridge. The cartridge has a connector member for attachment to the diaphragm, and has a filter member for filtering the fluid passing between the chambers. The first and second chambers have respective inlet and outlet ports. The connector member has an upset portion which bears against the diaphragm first surface. The connector member also has an extended portion, which extends through the aperture. The extended portion has a groove, which has a snap locking ring that bears against the diaphragm second surface. The upset portion and the snap locking ring provide a rigid cantilever attachment of the cartridge to the diaphragm. The extended portion also has a second groove, which has an O-ring seal that bears against the inner surface of the aperture for preventing fluid flow past the snap locking ring.
