A filter cartridge (1) is for a fluid filtration assembly (10). The filtration assembly (10) includes a bowl body (11) and a head body (12) having respectively a first and second collars (111, 121) to engage each other in rototranslation. The bowl body (11) has a filtration chamber (110) accessible through an access mouth (110′) delimited peripherally by the first collar (11) while the head body (12) has in the second collar (121) a slot (125). The filter cartridge (1) is housable in the bowl body (11) having a filter medium (2) and an end plate (3) to engage the first collar (111). The filter cartridge (1) is snap-blockable in the axial direction to the bowl body (11) by an active blocking member (31). The filter cartridge (1) includes an anti-rotation element (32) extending radially from the end plate (3) for being housed in the slot (125).

A cylindrical filter element having a central longitudinal axis and filter media including a plurality of radially extending pleats arranged in a pattern that repeats around the central longitudinal axis. Each of the pleats comprises an inner pleat tip, wherein the inner pleat tips of each pattern define an open area that extends along a height of the filter element, and wherein each pattern of pleats comprises a first series of intermediate pleats that descends in length from a major pleat to a minor pleat and a second series of intermediate pleats that ascends in length from the minor pleat to a major pleat of an adjacent pattern of pleats.

A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.

A filter device is provided with a filter element for filtering a fluid. The filter element has a filter medium body with an end plate arranged at an end face of the filter medium body in relation to a longitudinal axis of the filter medium body. A filter base housing receives the filter element. An assembly component for assembly and disassembly of the filter element in the filter base housing is connectable to the end plate and to the filter base housing by rotation about the longitudinal axis. The assembly component has interlocking elements. An interlocking counter element is arranged at the end plate. The interlocking elements can be brought into axial interlocking connection with the interlocking counter element, while enabling a free rotatability in rotational direction about the longitudinal axis. The interlocking counter element is a circumferential interlocking collar with insertion ramps for insertion of the interlocking elements.

An improved filter apparatus for a cryogenic fluid includes a filter and a support. The filter includes a mesh having an internal space and an open end. The support is associated with the mesh for maintaining a volume of the internal space above a predetermined value. In operation cryogenic fluid enters the internal space through the mesh and exits the open end thereof.

A filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing includes an alignment tab disposed on the second housing end. The alignment tab protrudes from the second housing end towards the first housing end. A filter element is positioned within the housing. The filter element includes a first endcap, a second endcap, and filter media positioned between and extending axially between the first endcap and the second endcap. The filter media defines a central opening extending axially therein. An alignment notch is disposed on the second endcap, the alignment notch protruding from the second endcap toward the first endcap.
