ABSTRACT:
A filter system comprising a tank and a filter assembly removably mounted therein. The filter assembly includes a plurality of filter tubes in fluid communication with a plenum chamber on the bottom thereof. The plenum chamber is open on its bottom, and rests on the bottom of the filter tank. Suitable seals maintain the fluid integrity of the plenum chamber against the bottom of the tank. The filtrate leaves the plenum chamber through an outlet port in the bottom of the tank.
The inlet port is also in the bottom of the tank, and the fluid to be filtered passes upwardly through a channel formed in the center of the plenum chamber. The top of the tank is sealed by a U-shaped gasket, with the cover of the tank resting on the gasket. No auxiliary flanges are needed to provide a top seal. The cover of the tank is raised by a lifting mechanism, and is rotatable away from the top of the tank to permit access to the tank. When the cover is to be returned to its closing position, a keying mechanism automatically seats the cover in the proper position.
