Disclosed are a filter element and a filter device using the filter element. The filter element includes: a base, wherein the base is installed on the filter device, and a first passage and a second passage are disposed at least partially in the base; and a filter body, wherein the filter body is detachably connected to an upper part of the base, the filter body has a filter space therein, a first filter passage and a second filter passage are connected and arranged on the two ends of the filter space, and a filter material for filtration is provided in the filter space. When the filter element is in a working state, the first filter passage and the first passage are connected for fluid communication, and the second filter passage and the second passage are connected for fluid communication.

A filter cartridge includes a casing. A filter medium is disposed within the casing. A female inlet port and a female outlet port are mounted to the casing at an end portion of the casing. The female inlet port is offset from the female outlet port along the radial direction at the end portion of the casing.

A filter assembly includes a manifold having a male inlet port and the male outlet port and a filter cartridge having a female inlet port and a female outlet port. The male inlet port and the male outlet port are mounted to a spool body such that the male inlet port and the male outlet port extend away from the spool body. The female inlet port and the female outlet port are mounted to a casing at an end portion of the casing. A related refrigerator appliance is also provided.

To move a filter along a manifold assembly the filter may be seated on a moveable shuttle assembly. Seating the filter on the shuttle assembly may include mating a key portion on the filter with a key portion on the shuttle assembly, each key portion corresponding to a filtration characteristic of the filter. The shuttle assembly and the seated filter may then be moved between a first position, wherein the key portions of the filter and the shuttle assembly are mated to one another and first and second fittings of the filter are spaced from first and second fittings of the manifold assembly, and a second position, wherein the key portions of the filter and the shuttle assembly are mated to one another and the first and second fittings of the filter sealingly engage the first and second fittings of the manifold assembly.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

A filter housing assembly is adapted for accommodating a filter element, and includes a housing member and a support structure. The housing member has a cylindrical body, a cap closure, and influent and effluent channels. The support structure includes a first support member that is provided on one of the cylindrical body and the cap closure, and a second support member that is provided on the other one of the cylindrical body and the cap closure. The first and second support members are adapted to be respectively connected to two open ends of the filter element such that one of the open ends is sealed and the other one of the open ends is connected directly to an outlet port of the effluent channel.

A water filter assembly is provided, including a filter head including a filter manifold in fluid communication with an existing water line, a head housing connected to the manifold and including landings, an elongate key member depending from a portion of the filter head, and a filter cartridge including a filter housing constructed and arranged to retain a supply of filter media, a filter closure attached to an upper end of the filter housing and having at least an inlet port and an outlet port, the closure configured for engaging the landings of the head housing and also having a recess constructed and arranged to matingly and slidingly accommodate the key member so that, upon engaging the filter head, the filter cartridge is in alignment with the filter head.

A manifold assembly including a guide rod, a method of moving a filter capsule along the manifold assembly, and a method of filtering fluid using the manifold assembly are provided.

A device and method for removing debris from a process fluid are described herein. Specifically, a sanitary disc strainer includes a strainer body, a moveable guide rod assembly, moveable within the strainer body, a plurality of grooved discs stacked on the moveable guide rod assembly, and an actuator for moving the moveable guide rod assembly to compress and decompress the plurality of grooved discs.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.
