Filter with quick-connect coupling

A filtration assembly, comprising

• an upright filter housing adapted to rest on a floor, and having an open upper end adapted to receive a replaceable modular filter;
• a cover removably secured to and closing the upper end of the housing, the cover defining inlet and outlet conduits for circulating fluid through the housing, the conduits terminating at a first set of openings in a substantially vertical face of the cover;
• an adapter block having inlet and outlet conduits adapted for connection to fluid supply and delivery lines, the conduits terminating at a second set of openings in a substantially vertical face of the block;
• the first and second sets of openings respectively being substantially in mating alignment, one of the sets of openings being encircled by domed convex seats defined by the associated vertical face, and the other set of openings being encircled by resilient seals captively retained in recesses in the associated vertical face, whereby the assembled housing and cover can be fluid connected to and unconnected from the adapter block by horizontal movement of the housing and cover along the floor, and without requiring additional vertical clearance space;
• and
• means for securing the block to the cover so the seals are urged together in mating engagement, whereby the domed convex seats effect a face seal against said seals and around the respective sets of respective openings.
