Technologies are generally described for a two-piece filter assembly for centrifugal pump assemblies. A filter portion optionally made from recyclable material may receive contaminated oil from the oil path, through the filter, and provide the filtered oil back to the sump. The filtered oil is then reclaimed by the oil ring from the sump to lubricate the bearings. The filter portion may be removable from the plug portion and the plug portion may be placed back onto the pump assembly with a new filter portion. In some examples, moisture absorbing beads are placed inside the filter portion to remove moisture from the filtered oil.

A rechargeable spin-on filter includes a cover, a housing threadably joined with the housing, and a filter element can be 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 bottom plate can be reinforced with an optionally metal reinforcing plate that registers and locks relative to the bottom plate via locking elements, in the form of corresponding apertures and projections or tabs that interfit with one another. A related method is provided.

A water filter assembly for a refrigeration appliance contains an inlet connection, a filter head, on which a water filter can be mounted, a non-return valve and an outlet connection. The non-return valve is connected to the water filter by way of a hose. The hose can be attached to a connection of the filter head which is already available to feed or drain water, without adjustments to the filter head being required for this purpose.

A filter assembly includes a manifold having an inlet and outlet port. The filter assembly further includes a filter cartridge. The filter cartridge includes a casing and a filter casing disposed within the casing. The filter cartridge also includes a gear rack, and an inlet and outlet port. The filter assembly further includes an electric motor configured to move the filter cartridge along an axial direction by rotating a gear coupled to the electric motor such that the gear meshes with the gear rack. The filter cartridge is movable between a first position in which the filter cartridge and manifold are not in fluid communication, and a second position in which the filter cartridge and the manifold are in fluid communication. A refrigerator appliance having the filter assembly is also provided.

A filter cartridge has media construction, a housing, and a first end construction. The first end constructions includes an outer radial wall with circumferentially spaced connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle. The filter cartridge is removably attached to a filter head, which has mating connecting segments. A bowl cartridge assembly is also provided including connecting sections with a plurality of helical profiles.

A health meter with decontamination device for contaminated fluid with a metal casing body with sealable metal lid, inlet port and outlet port, a removable open bucket having a docking lid and a plurality of openings, a hollow tube with an opening connected to an outlet port, a convex reinforcing spacer in the removable open bucket, a compressible decontamination media and a reinforcing seat in the removable open bucket. Contaminated fluid flows into the metal casing body between the removable open bucket and metal casing body through openings in the docking lid into the compressible decontamination media sequentially into the hollow tube and out the outlet port while an inlet and outlet electrode and two sensors in the media communicate with a controller via a network to a plurality of client devices for automatic remote monitoring.

An apparatus facilitates multiple paths or circuits through an engine and remote housing for an oil filter. The apparatus includes a first oil filter chamber housing a first oil filter, a second oil filter chamber housing a second oil filter, a first output of the remote housing configured to provide a path from the first oil filter chamber housing to bearings of an engine, a second output of the remote housing configured to provide a path from the second oil filter chamber housing to a sump of the engine, and an input of the remote housing configured to provide a path from an oil pump of the engine to the first oil filter chamber housing.

A filter device for treating fluids, in particular for filtering fluids such as fuel, oil, or water, has a housing (56) with a housing pot (58), a housing cover (60), at least one inlet (88) for the fluid to be treated, and at least one outlet (82) for the treated fluid. A connecting head (12) has at least one feed (16) for the fluid to be treated and connectable to the at least one inlet (88), and/or at least one discharge (18). The connecting head (12) and the treatment element (14) can be connected to each other by means of a releasable bayonet-type connecting device (34) through the execution of a rotational/plug-in movement about a connecting axis (20) of the treatment device (10).

A low-profile, large diameter, oval shaped, modular, inside out flow in-tank filter assembly includes at least one filter element having spaced first and second identical endcaps each with a central opening there through and filter media extending between the endcaps. The filter assembly includes a tank bushing coupled to the central opening of one endcap of at least one filter element on one end of the assembly, wherein the tank bushing is configured to mount the inside out flow in-tank filter assembly to a return line within a reservoir. The filter assembly includes a bypass valve coupled to the central opening of one endcap of at least one filter element on one end of the assembly, wherein the bypass valve is configured to allow flow to selectively bypass the filter media of each filter element. Further, each endcap includes a universal alignment and coupling structure around the central opening.

A filter assembly for filtering water in spas, swimming pools, hot tubs and whirlpools, having a first or outer filter element, a second or inner filter element removably installed within the outer filter element, a first coupling member associated with the outer filter element, a second coupling member associated with the inner filter element, the first and second coupling members engaging one another to connect the inner filter element with the outer filter element, and a releasable detent arrangement resisting disengagement of the first and second coupling members from one another. The outer filter element includes a filter medium for mechanically removing particulates from a fluid to be treated and the inner filter element includes a filter medium containing fluid purifying particles.
