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.

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 filter device having a filter housing (2) and a filter element (15) accommodated therein, the element material (44) of which for filtering a liquid extends between two end caps (40, 42), at least one end cap (40) of which is mounted on an element receptacle (14), wherein a bearing (46, 54), providing more than one degree of freedom, is used to articulate the filter element (15) on the element receptacle (14) via its one end cap (40), characterized in that the bearing has a convex bearing surface (46) that is guided in a concave bearing surface (54) and in that the respective bearing surface (46, 54) is part of a shell (55a, 55b), at least one (55b) of which has a passage (55c) for liquid media.

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 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 portable water conditioning system is provided that includes a water conditioner, a first sensor, a second sensor, and a controller. The water conditioner has a plurality of conditioning stages that condition water. The plurality of conditioning stages include, in a direction of flow of the water through the water conditioner, a reverse osmosis stage and a deionizing stage. The first sensor detects a first condition of the water before the reverse osmosis stage. The second sensor detects a second condition of the water after the reverse osmosis stage. The controller is in communication with the first and second sensors and determines a health status of the reverse osmosis stage based the first and second conditions. The first and second conditions each include a level of total dissolved solids of the water.

Disclosed is a filter coupling device having joint members, a base plate, a filter holder, a rotation shaft, and a leg. The filter holder allows support of a first filter and a second filter. The rotation shaft is connected with the filter holder. The filter holder takes a first attitude and a second attitude by rotating around the rotation shaft. The filter holder includes a first filter holder configured to support the first filter in the first attitude, and a second filter holder configured to support the second filter in the second attitude.

A center tube and a central fluid supply tube combination includes a center tube body defining a longitudinal length, and a central reservoir. The center tube also includes an apertured annular wall extending axially the majority of the longitudinal length, and a first annular solid wall extending axially from the apertured annular wall. A central fluid supply tube is disposed in the central reservoir, and includes a second annular solid wall that is radially surrounded by the apertured annular wall of the center tube. The second annular solid wall defines a supply passage with a fully circular flow flux.

A pedestal for use with a canister filter system and a filter element for positioning and retaining the filter element in the canister filter system includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. Also, the pedestal includes an annular wall that terminates at a bottom free end, and that defines a slot that extends axially upwardly and circumferentially from the bottom free end. A flow aperture extends through the annular wall that is disposed axially above the slot.

A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises at least one lock notch spaced around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to mate with the lower collar. The upper collar has at least one housing that is coupled to the upper collar, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch. A pair of pipeline filter assemblies, wherein at least one connection plate is used.
