Patent number: 7416663Abstract: A replacement filter cartridge assembly for hot tubs, spas and other aquatic environments includes a top end cap, a bottom end cap, a perforated elongated core extending between the end caps, and a pleated filter medium situated between the end caps and disposed circumferentially about the core. The replacement filter cartridge assembly is removably rotatably attachable to an adaptor of a filtering apparatus having a pair of diametrically opposed prongs extending outwardly therefrom. The bottom end cap has a central opening and a pair of diametrically opposed notches situated at the periphery of the central opening. The replacement filter cartridge assembly includes an internal lock ring which is situated on the core at the bottom end cap. The internal lock ring has one or more surfaces which engage the prongs of the adaptor to removably secure the replacement filter cartridge assembly to the adaptor of the filtering apparatus.Type: GrantFiled: April 14, 2006Date of Patent: August 26, 2008Assignee: Pleatco Electronic & Filter CorporationInventors: Leonard B. Kott, James Tormey

Patent number: 7407058Abstract: A filter element for filtering fluids has at least one filter unit (12, 14, 16) that is disposed concentrically around the axis of the element. The unit is supported on at least one supporting element (24, 26, 30) in the direction of the flow of the fluid. At least part of the supporting elements (24, 26) is provided, at least on the side facing the filter unit (12, 14, 16), with channels (28) for guiding the fluid. Longitudinal ribs (50) delimit the channels (28), and extend along the supporting element (24, 26) in the form of spiral tracks. The two free ends of each channel (28) emerge at opposite ends of the corresponding supporting element (24, 26). The channels (28) extend continuously along the supporting element, are devoid of multiple deviations in the fluid flow and only partially surround the corresponding supporting element (24, 28) to form a torsional guide for the fluid flow.Type: GrantFiled: May 23, 2003Date of Patent: August 5, 2008Assignee: Hydac Filtertechnik GmbHInventors: Helmut Mertens, Andreas Schunk

Patent number: 7407057Abstract: A plastic transmission filter (1) composed of mating upper (2) and lower (3) shells of synthetic resin material with at least one set of registering weld posts (10) extending between inner surfaces of the upper and lower shells; a fluid pervious centertube (4) interposed between the mating shells around the weld posts, and a filter material (5) wrapped around the centertube to form a bag filter. The filter assembly can be welded together in a single vibration welding operation and provides enhanced flow of transmission fluid by avoiding flow restrictions caused by prior art reinforcement poles.Type: GrantFiled: September 17, 2003Date of Patent: August 5, 2008Assignee: Mann & Hummel GmbHInventors: Kevin Vichinsky, Stuart Miller, Bruce Bounnakhom

Patent number: 7404493Abstract: The present invention provides a filter that can minimize the amount of residual liquid within the housing or container with a simplified construction. The article includes a cylinder portion having a cylindrical internal space with both ends open, a cylindrically formed pleated filter 5 inserted in the internal space of the cylinder portion 3 in contact with the inner wall of the cylinder portion 3 and having upper and lower edges liquid-tightly sealed. A perforate inner core 7 supports the inner surface of the pleated filter 5, lower and upper end caps 9, 11 are liquid-tightly bonded to the respective ends of the cylinder portion 3. A liquid distribution passage 21 communicates with gaps between the pleats of the pleated filter 5 from the lower portion of the cylinder portion 3. A liquid feed inlet 15 communicates with the liquid distribution passage 21 formed between the periphery of the pleated filter and a tapered inner wall surface 8 of the cylinder portion 3.Type: GrantFiled: March 23, 2005Date of Patent: July 29, 2008Assignee: Entegris, Inc.Inventor: Fumio Nozaki
