摘要： Disclosed is a unique filter assembly for ensuring replacement cartridge compatibility in filtration systems having replaceable filter cartridges with lugged mounting systems. One representative filter assembly includes a representative cartridge member having a body portion for enclosing filter media and a neck portion depending therefrom. The representative neck portion of the representative cartridge includes at least one axial inlet port for directing unfiltered fluid into the body portion and at least one axial outlet port for directing filtered fluid out of the body portion. The representative neck portion also has at least two representative lugs depending radially outwardly therefrom, wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface. The at least two representative lugs wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface could be operatively positioned on other components of the representative filter assembly as well.

摘要： An encapsulated filter cartridge is disclosed, which includes a filter assembly including a carbon block filter element and a microporous filter element. The filter cartridge has a permanently sealed sump defining an interior chamber configured to accommodate the filter assembly, the sump having an inlet for permitting unfiltered fluid to enter the interior chamber for communicating with the radially outer surface of the filter assembly and an outlet for permitting filtered fluid to exit the interior chamber from the axial portion of the filter assembly. The microporous filter element of the filter assembly may include a hollow fiber subassembly housed within the axial cavity of the carbon block element, said fiber subassembly including a plurality of hollow microporous fibers, or a pleated filter element surrounding the radially outer surface of the carbon block element.

摘要： Se proveen cartuchos de materiales filtrantes que tienen derivaciones ajustables, y sistemas y métodos que los usan. Los aspectos incluyen un cartucho filtrante de derivación ajustable en donde una corriente tratada y una corriente no tratada ajustada se combinan antes de la posfiltración y el porcentaje o la relación del agua tratada y no tratada se puede ajustar en el momento de instalación desde el exterior del cartucho filtrante con un nivel conocido o predecible de derivación. Los cartuchos de materiales filtrantes comprenden: una entrada en comunicación continua con una cámara de alimentación y una salida en comunicación continua con un compartimiento de mezclado; un compartimiento del material filtrante que contiene un material filtrante; un puerto de derivación en comunicación continua con la cámara de alimentación y el compartimiento de mezclado. Estos cartuchos se pueden ajustar para satisfacer las necesidades de una variedad amplia de usos finales.

摘要： Provided are media cartridges that have adjustable bypasses, and systems and methods that use them. Aspects include an adjustable bypass filter cartridge where a treated stream and an adjusted non-treated stream combine prior to post-filtration and the percentage or ratio of treated the and the non-treated water is adjustable at the time of installation from the outside of the filter cartridge with a known or predictable level of bypass. Media cartridges comprise: an inlet in fluid communication with a feed chamber and an outlet in fluid communication with a mixing compartment; a media compartment containing a media; a bypass port in fluid communication with the feed chamber and the mixing compartment. Such cartridges can be adjusted to meet the needs of a wide variety of end uses.

摘要： A valve assembly is disclosed for use in conjunction with a replaceable filter cartridge system. The valve assembly includes a head member having an interior valve chamber defining a central axis, and inlet and outlet passages extending parallel to and communicating with the interior valve chamber. The valve assembly further includes a valve member having an inlet path and an outlet path, adapted for rotation within the interior valve chamber of the head member between a filter position wherein the inlet path of the valve member is in communication with the inlet passage of the head member and a bypass position wherein the inlet path of the valve member is out of communication with the inlet passage of the head member. The valve assembly further includes a seal member seated in an upper surface of the valve member and positioned to seal against an opposing surface of the interior valve chamber. The seal member sealingly isolates untreated and treated fluid streams flowing through the inlet and outlet paths of the valve member, respectively, when the valve member is in the filter position, and sealingly isolates the inlet and outlet passages of the head member from the atmosphere when the valve member is in the bypass position to permit fluid to flow therebetween.
