摘要： A combination filter element comprising a bundle of hollow microporous fibers (48) housed within an extruded carbon block (44), wherein the carbon block is fabricated to balance particle retention capacity against absorption capacity to provide a composite filter with desirable pressure drop, filter life, and particulate and chemical contamination reduction, and a filtration device, in which the combination filter element may be employed, having a base portion (14) including a sump (32) which has an inlet (28) and an outlet (30) for receiving the filter element.

摘要： A filter cartridge configured to provide two or more levels of fluid filtration or conditioning from within a single filter cartridge is disclosed, the filter cartridge including a housing that defines an interior cavity and has an inlet portion for receiving fluid into the cavity, a first outlet portion for discharging fluid from the housing, and a second outlet portion for discharging fluid from the housing. The filter cartridge also includes a first stage filter disposed within the interior cavity for conditioning fluid passing therethrough, the first stage filter in fluid communication with the inlet portion and the first outlet portion by way of a first flow path, and a second stage filter disposed within the interior cavity of the housing for conditioning fluid passing therethrough, the second stage filter in fluid communication with the inlet portion and the second outlet portion by way of a second flow path.

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.
