A biocide-generating device including a housing having an inlet and an outlet. The biocide-generating device additionally including a strainer basket that mounts within an interior of the housing including parallel electrode plates positioned within an interior of the strainer basket. The biocide generating device additionally including a protective dielectric sleeve in which the electrode plates are received. The protective dielectric sleeve is positioned between the electrode plates and the strainer basket.

A seal arrangement for a filter for fluid-tight sealing between a filter element and a filter head includes an annular elastic seal, a filter head sealing face and a filter element sealing face. The seal has a filter head side facing the filter head sealing face, a filter element side facing the filter element sealing face, an inner face running circumferentially on the inner side, and an outer face running circumferentially on the lateral side. The filter head side has a circumferential first recess between the inner and outer faces. The filter element side has a circumferential second recess between the inner and outer faces. The seal arrangement is configured in such a way that the seal, when subjected to a pressure from the inner face and/or from the outer face, is wedged in the direction of the acting force, between part faces of the sealing faces that narrow toward the middle.

A filtration system includes a housing and a filter element positioned within the housing. The housing includes a first housing end and a second housing end. A drain opening is defined in the second housing end. The filter element includes a first endplate and a second endplate defining an endplate opening. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A drain plug axially protrudes from the second endplate in a direction away from the filter media. The drain plug is configured to engage the drain opening and facilitate installation of the filter element into the housing. A lid is configured to engage the first housing end. The engagement between the lid and the first housing end occurs when the drain plug is disposed within the drain opening.

A rechargeable spin-on filter includes a cover, a housing threadably joined with the housing, and a filter element that can be removed and replaced with another filter element relative thereto. The cover and/or housing can be plastic. The cover can include a bottom plate having inlet ports and an outlet port. The filter element can include an end cap defining a perimeter about an inner dimension, such as an inner diameter. The cap can define a groove to receive a rib of a support tube over which the element is installed. Alignment of the rib and groove can index and register the element with the support tube. A related method is provided.

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 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.

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.

A spin-on filter assembly with replaceable coreless element comprises: a reusable spin-on housing including a filter bowl having sealing structure on a bottom of the filter bowl and a sealing structure on a top of the filter bowl; a center support tube integral with the filter bowl and including a perforated tube and an upper portion having an threaded coupling allowing for the filter assembly to threaded into position and an exterior sealing structure; and a replaceable coreless filter element mounted on the central support tube within the filter bowl and having filter media, a lower sealing structure configured to engage with the sealing structure on the bottom of the filter bowl and an upper sealing structure configured to engage with the exterior sealing structure on the center support tube.

A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.
