摘要： A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be larger in cross dimension than the port. The filtration element can be a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element.

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 surface formation.
