A liner for a filter sub-assembly has a wall having an innermost surface that bounds a cavity extending between opposing first and second ends of the liner. The wall has a deflected portion extending into the cavity and delimiting an opening. The liner may be used in a rotor of a filter assembly.

The filter device includes a case, an element, and a water separator. The case accommodates the element and the water separator. The element removes solid particulates from the fuel. The element can be replaced by opening the case. The water separator removes water content from the fuel. The water separator is held in the case. The water separator is movable relative to the case. The water separator is movable within a movable range. The element and the water separator are provided with a passage connecting member for connecting a fuel passages.

An inline-type strainer including a drain line and a screen configured to be attachable to and detachable from a housing is provided. A screen is supported to be attachable to and detachable from a lid. A lid coupling mechanism that couples a housing and the lid when the lid is attached to the housing is provided between a bottom surface of the housing facing the filter chamber and a lower end of the lid. A lower discharge flow path is formed in a lower coupling element on a side close to the housing constituting the lid coupling mechanism, and an upper discharge flow path is formed in the upper coupling element on a side close to the lid constituting the lid coupling mechanism. When the lid is attached to the housing, a coupling state is established between the upper and lower coupling elements, and the upper and lower discharge flow paths communicate with each other, and thus a drain line is constructed.

Certain embodiments include a screen assembly of a vessel, where the screen assembly includes a plurality of fixed elements and a retainer, and the retainer includes a ring, a plurality of wedges disposed about the ring, and a plurality of keyholes at spaced locations about the ring. Each keyhole includes a bore and a slot extending from the bore into an adjacent wedge of the plurality of wedges, the slots have a width less than the bores, and the retainer may receive the fixed elements through the bores and may be rotated in a relation with the plurality of fixed elements to bring the plurality of fixed elements into simultaneous engagement with the wedges.

Disclosed herein are decanting backwash receiver assemblies, and related methods of fabrication and use. The present disclosure provides improved decanting backwash receiver assemblies for decanting of input feeds, and improved systems/methods for utilizing and fabricating the decanting backwash receiver assemblies. The present disclosure provides decanting backwash receiver assemblies utilizing porous media insert members and/or porous media surfaces for the decanting of input feeds. Exemplary decanting backwash receiver assemblies are configured and dimensioned to receive a filter backwash surge flow of slurry (e.g., solids and liquid mixture), and provide for settling of the solids from flow 11, and provide for decanting of a liquid layer above the settled solids, and optionally provide for de wetting the settled solids, and provide for discharge of the settled solids (e.g., liquid wetted) from the bottom of the assemblies.

Filter elements and filter systems are provided. The filter element allows for a reversed flow of fluid through the filter element when flowing from a first port to a second port of a filter head of the filter system. The filter element includes a standpipe in a central cavity of a tube of filter media that is fluidly connected with an exterior of the tube of filter media by a radial flow conduit and an axial flow tube.

The retainer includes a first metal plate member 10A or 40A in which flow-path forming members having a predetermined curved shape or a linear shape are arranged on the same plane in parallel to each other at a predetermined interval to form a donut shape as a hole, and a second metal plate member 10B or 40B having a configuration equivalent to that of the first metal plate member, wherein crossings of the flow-path forming members configuring the respective metal plate members are fixed with the second metal plate member stacked on the first metal plate member, and the flow-path forming members 15A or 50A configuring the first metal plate member and the flow-path forming members 15B or 50B configuring the second metal plate member form a line symmetric shape in plan view.

A variable configuration modular fluid filter assembly includes one or more discrete filter housing assemblies that each include a mount body constructed to support a cap and a filter sleeve. A plurality of bosses are formed on radially outward facing sides of the mount body and are each discretely selectable to fluidly connect the discrete mount body to one another to provide a desired flow characteristic of the discrete filter assembly arrangement. Preferably, each discrete filter assembly includes a seal arrangement disposed between the cap and the mount body and which orients the sealing interface therebetween at an acute angle relative to an axis of rotation of the cap relative to the mount body when the cap and mount body are engaged with one another.

The filter includes a body, cap, and a filter media. The body includes an internal chamber and a plurality of perforations exposing the internal chamber. A filter media is positioned and retained in the internal chamber such that it covers the plurality of perforations. The internal chamber is in fluid communication with a water fill hose so as to receive water and dispense the water out of the body through the plurality of perforations after having passed through the filter media. The cap is adapted to cover the open top of the body. The cap includes a threaded passage for receiving a male threaded connector on the hose. The internal chamber is preferably filled with sanitizer preferably selected from a group consisting of an oxidizer and chlorine.

A water sediment filter assembly includes a screen member and a drain port which permits the removal of collected debris. The water sediment filter assembly includes a valve member which can be moved to different positions to permit the draining of collected sediment through the drain port.
