CA 2391147

A liquid filter apparatus includes a filter media belt enclosed by sealably mated cover pan and floor pan defining a vacuum chamber connected to a sealed clean liquid tank, with clean liquid pumped out continuously to draw liquid to be filtered into an upper region of the filter chamber via on inlet hose connected to a source of liquid to be filtered. The cover pan is lifted after the vacuum is relieved to allow indexing of the filter media belt. A main control valve to the clean liquid tank is closed and pumping liquid continues during indexing. A vacuum control device limits the maximum vacuum developed in the clean liquid tank and a vacuum pump removes air from the tank for priming and to eliminate excess accumulated air.
