ABSTRACT:
Removable filter cartridge assemblies (10) for housings (28) having a removable member (101, 130) to provide access to the interior (102, 136) of the housing and an inlet (108, 134) and an outlet (109, 135) to and from the interior thereof (102, 136) comprising at least one filter cell (12) through which fluids are passed for filtration, the cell having a central aperture (18) therethrough for the passage of fluid, separate from the fluid within the housing; opposed disks of filtration media (16), spaced apart and defining upper (16U) and lower (16L) surfaces of the cell emanating radially from the central aperture; and, an outer peripheral edge (14) circumscribing the cell; first and second retainer ring members (22) securably disposed on the upper and lower surfaces of said filter cell, open to and concentric with the central aperture, said first retainer ring members being contiguous with the outlet of the housing; and lifting means (42, 50, 80, 90) communicable with one of the retainer ring members for movement of the filter cell into and out of the filter housing. The present invention also provides a device for lifting and carrying a filter cell (12) comprising retainer ring members (22); and a lifting device (42, 50, 80, 90) in communication with said retainer ring members, as well as a device for lifting and carrying a filter cell (12) comprising an outer peripheral edge (14) provided by said filter cell; and a lifting device (70) in communication with said outer peripheral edge. The present invention also provides methods for the assembly of a cell-type filter cartridge device disposed within a filter housing and a method for removing a filter cell cartridge assembly from a filter housing.
