A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

A pedestal for use with a canister filter system and a filter element for positioning and retaining the filter element in the canister filter system includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. Also, the pedestal includes an annular wall that terminates at a bottom free end, and that defines a slot that extends axially upwardly and circumferentially from the bottom free end. A flow aperture extends through the annular wall that is disposed axially above the slot.

An extraction cell cap assembly allows for toolless disassembly. The assembly includes a cap body having a threaded base releasably engaged with a cell vessel, a support member extending axially upward from the base, and a bore axially extending through the support member. The assembly also includes a locking cap having a plunger slidably received within the bore, a recess disposed within the plunger, and a locking portion that releasably engages the support member. Rotation of the locking cap in a first direction engages the locking portion with the support member, and rotation in an opposite direction disengages the locking portion. A filter is received in the recess and a seal member received in the bore, wherein the seal member forms a fluid-tight seal between the cell vessel and the assembly when the locking portion and the support member are engaged and the assembly is secured to the cell vessel.

A filter manifold is provided for processing fluid being provided to a fluid dispenser, featuring a new and unique combination of a mounting bracket, a filter cartridge and an accumulator cartridge. The mounting bracket is configured with porting connections. The filter cartridge may include a filter cartridge porting connection configured to plumb into one of the porting connections on the mounting bracket and also configured to filter the fluid being provided to the fluid dispenser. The accumulator cartridge includes an accumulator cartridge porting connection configured to plumb into another one of the porting connections on the mounting bracket and also configured to receive, accumulate and provide the fluid to the filter cartridge to be filtered before being provided to the fluid dispenser.

Disclosed is a filter device having a filter housing (10) that comprises at least two ports (12, 14), such as an inlet for unfiltered matter and an outlet for filtrate, and accommodates a replaceable filter element (16), which is characterized in that by a shut-off device (18) a fluid-conveying connection between the inlet (12) and the outlet (14) that exists in an open position, is blocked in a blocking position, and in that by an actuation device (20) the shut-off device (18) can be brought into these individual positions.
