    Abstract: A head for a water filter system having a filter element including a three-way valve member movable between a first position, a second position, and a third position. When the valve member is in the first position, incoming water is directed to the filter element to remove sediment and impurities from the water. When the valve member is in the second position, the incoming water is blocked from passing through the filter element and the valve member. Lastly, when the valve member is in the third position, the incoming water passes through the valve member and not the filter element so that the filter element can be removed and replaced without interrupting the incoming water flow.

    Abstract: A fuel water separator (FWS) filter that is configured to permit water to be drained from the water sump of the FWS filter without shutting off fuel flow to the FWS filter. A check valve is positioned between the water sump and the filter element. When the FWS filter is under vacuum (e.g. as in operation), the check valve can be closed to allow water to drain from the sump. The check valve can close automatically by floating on accumulated water in the sump until the water rises to a level where the check valve is closed. The check valve can also close by opening the drain valve of the FWS filter, which causes a differential pressure between the sump and the vacuum created in the filter element chamber, which forces the check valve to close.

  • Publication number: 20120223002
    Abstract: Disclosed is a capsule apparatus having a filter housing defining a filter chamber with a top cap having a plurality of ports extending substantially laterally from a top end of the top cap to reduce the overall dimensions of the apparatus. The lateral and substantially uniform orientation of the ports facilitates connection to panel mount assemblies and improves filter maintenance processes. A transfer tube extending the length of the capsule allows the introduction of heated fluids from a top mounted inlet port to a bottom of the capsule chamber to allow or a substantially uniform heat gradient in the capsule filter chamber. An alternative shield secured in the housing defines a first chamber in fluid communication with an inlet and a second chamber wherein the two chambers are in fluid communication via an opening defined by a lower end of the shield and a bottom of the filter chamber.

  • Publication number: 20120199529
    Abstract: The invention relates to a filter comprising at least one first (2) and at least one second filter medium (3), said filter media defining therebetween a flow space (4) in which a device (5) for separation and flow guidance is inserted and divides the flow space such that a functional space (25, 26) is disposed adjacent to the first (2) or the second filter medium (3), respectively. The first filter medium (2) defines a hollow space (21) toward the outside and the second filter medium (3) defines a hollow space (22) toward the inside, and each of the hollow spaces (21, 22) can be connected to at least one fluid duct (23, 24). The filter is characterised in that the flow space (4) comprising the two functional spaces (25, 26) thereof can be connected to at least one further fluid duct (27) that is separated in a fluid-tight manner from the other fluid ducts (23, 24).

  • Patent number: 8225863
    Abstract: A modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules.

  • Patent number: 8221617
    Abstract: An apparatus for reclaiming hot process water from a animal processing facility includes a screen portion, a filtration portion and optionally a UV sterilization portion. The screen portion receives dirty hot process water and removes macroscopic debris to produce raw tank water. Raw tank water is pumped through the filtration portion at relatively high pressure in order to remove substantially all solids to produce a permeate side stream. The permeate is optionally passed through a very intense ultra-violet field in order to produce uncontaminated reclaimed hot process water which may be safely reintroduced as hot scald water for the poultry cleaning process.

  • Patent number: 8216467
    Abstract: A filter device has a filter housing (1), at least one filter element (13) received in the filter housing (1) and an inner fluid space (71) limited by a filter medium (17) through which the fluid to be cleaned can flow. The filter medium separates the inner fluid space (71) from an exterior fluid space (11) located in the filter housing (1). The filter housing (1) has a fluid inlet (7) and a fluid outlet for cleaned fluid. A fluid guide device (9) is connected downstream to the fluid inlet (7) and can be optionally retrofitted to form a flow path between the fluid inlet (7) and the exterior fluid space (11) or between the fluid inlet (7) and the inner fluid space (71) disposed in the filter element (13).

  • Publication number: 20120074073
    Abstract: A concentrator is used for concentrating a fluid, particularly a plasma component out of blood, for treatment of a patient. The concentrator apparatus includes a main housing defining a centrifuge chamber, that also holds the filter. The concentrator allows viewing of the fluid after centrifuging, with an outlet port positionable at a height corresponding to the level of the fraction of the fluid to be further concentrated. Once the fluid is centrifuged, a portion of the fluid is drawn through the outlet, and then pressured past the filter to further concentrate the fluid using the same vessel as used for centrifuging. The same plunger is preferably used to draw centrifuged fluid from the centrifuge chamber as to pressure the centrifuged fluid past the filter.
