Abstract: A filter device includes a plurality of filter elements (21) received in a filter housing having a filter inlet for a fluid to be filtered and a filter outlet for the filtered fluid. Flow through the filter elements (21) is possible in both directions for filtration or backwashing. Because the shut-off element (41) is a fast-closing plate valve (43) actuated by a hydraulic piston (53) and blocks the fluid connection so quickly, a feeding effect is created in the manner of a pressure blow on the backwashed filter element (21). The feeding effect increases the cleaning of pollution on the filter element (21), achieving an improved backwashing cleaning.

Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore and a valve body received at least in sections thereof in the valve bore. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to a valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and transferred from the open state into the closed state. The valve body, upon transfer of the water drainage device from the closed state into the open state, moves linearly along the longitudinal axis of the valve bore and away from the valve seat along or at a slant to a direction of gravity in downward direction.

Abstract: A filtration system and method of using the same. The method comprises the steps of guiding, by alignment rail and mating boss, a filter cartridge into a manifold housing; aligning a filter magnet with a corresponding manifold magnet; rotating, by attractive magnetic forces, the manifold magnet upon rotation of the filter cartridge into an installed position; and actuating, by attractive magnetic forces, a manifold valve.

Abstract: A filter apparatus (10) has a plurality of filter elements (20) in a filter housing (12) having a filter inlet (50) for a fluid to be filtered and a filter outlet (52) for the filtered fluid. A pressure control device (42) has at least one control plate (58) located inside a connection chamber (14). The control plate laterally passes over individual upper element openings (54) of the filter element to be backwashed (20), in a predefinable sequence, covering the opening to an increasing degree and then exposing the opening again. A discharge opening (46) of the backwash device (44) is, at least in part, fluidically connected to a lower element opening (56) of the filter element (20) to be backwashed, as the pressure control device (42) moves towards the upper element opening (54).

Abstract: A filter unit includes a body portion that receives a water filter. An engaging portion is coupled to the body portion. A bypass actuator rotates relative to the engaging portion to rotationally and axially operate a bypass valve of a fluid manifold. The bypass actuator drives axial engagement of the engaging portion with a valve assembly of the fluid manifold. The bypass actuator extends through the body portion and the engaging portion.

Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

Abstract: A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism (52, 54) that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.
