    Abstract: A two-stage, retrofit filter is adapted for use with an electrical discharge machine (EDM) includes nested inner and outer filtering elements that may be placed as a unit in the same tank and over the apertured standpipe used for a one-stage filter, such that the fluid to be filtered now flows through each of the multiple filter elements. The retrofit EDM filter may be configured for flow in either direction, though the usual arrangement is one whereby the fluid being filtered flows up through the bottom of the tank, out the apertured standpipe, and into the inner filter element. Preferably, the filter elements are cylindrical, pleated elements composed of a technical grade filter paper. In the preferred embodiment, a pressure-operated release valve is provided in conjunction with the inner filter, such that when a predetermined pressure is reached due to the entrapment of contaminants by the inner filter, the valve opens to allow the fluid to be filtered to flow through the outer filter.

    Abstract: An improved disposable filter cartridge for use in a filter housing includes a pleated filter member and first and second plastic end caps mounted to the ends of the filter member. The first end cap has an inner edge defining a central opening. In one embodiment, an elastomeric annular gasket is removably mounted to the inner edge of the first end cap. In another embodiment, a predetermined surface of elastomeric annular gasket is adhered to a confronting surface of the first end cap. At least one annular ridge projects into the first end cap opening. The at least one ridge abuts the outer surface of an inlet tube to form a fluidic seal with the inlet tube when the disposable filter cartridge is mounted within a cooperative filter housing. The second end cap may include an elastomeric annular gasket having an angled sealing surface configured to form a seal against the confronting end of an inlet tube.

    Abstract: A filter for a fluid system includes a housing having an interior cavity. A filter media is disposed in the housing and defines a central opening. A center tube is arranged within the central opening and includes a plurality of helical fins extending radially outwardly from a central portion of the center tube. The helical fins terminate in an outer portion that is adjacent to the filter media. The center tube provides the desired structural integrity while permitting fluid to flow through the center tube. The present invention center tube is produced by a plastic extrusion process.

    Abstract: A filter element for end face inlet formed of triangular channels which are alternately closed such that the fluid to be filtered must pass through the filter material in order to flow from the inlet side (22) to the discharge side (23). The channels are formed by alternating flat layers (17) and folded layers (18), whereby all sides of the inlet channels face a discharge channel. A particularly high filter efficiency is thereby achieved such that a large filter surface area and a high filter capacity are attained with a relatively small structural volume. The filter can be used, for example, as an air filter for various air filtration applications.

    Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.
