Duplex Lube Oil Filter

Two cylindrical housings are connected via inlet and outlet valves. The valves are linked by a common gear box with a hand wheel that allows selection of a clean housing without interruption of the oil flow. Oil enters the top of the housing, and particulates are trapped within the elements as the oil passes through. When a predetermined differential pressure is reached, changeover to a clean housing is accomplished, automatically or manually. The cover hold-down bolts and vent valve associated with the out of service housing become exposed and this allows the dirty filter elements to be cleaned or replaced without interruption of flow.
