An upper plate provided on upper ends of a filtration member and an inner tube includes a tubular portion along the inner tube, a rib formed so as to protrude inward in a radial direction from an inner circumference of the tubular portion, and a hole formed in the rib. A gripping member has a protrusion portion that protrudes downward from a body portion having a thick plate shape inserted into a hollow portion of the tubular portion. When the gripping member is mounted on the upper plate, the protrusion portion is inserted into the hole.

In one embodiment, a flexible oil filter bib comprises an open end, a closed end, and upper and lower side panels, an oil filter removal aperture configured to permit access by an oil filter removal tool and graspable tabs configured to secure a portion of the bib under the oil filter. In some embodiments, a disposal compartment is configured to receive a removed oil filter and used oil. In some embodiments, a folded edge is formed at the open end of the bib to further contain used oil. In particular embodiments, one or more pockets can receive an end of an elongate tool to facilitate positioning the bib. In another embodiment, a bag is placed at least partially around an oil filter by placing a lower portion of the bag under the fixed end of the oil filter and inserting a tool through an aperture in the bag to remove the oil filter, allowing it to fall into the bag.

A support apparatus for a filter membrane comprises a base support and a disc-shaped porous support member. The member is removably received in a seat portion of the base support in fluid communication with a drain. A bottom side of the disc-shaped porous support member is supported in a support plane. The bottom side of the member is unsupported in an area and the unsupported area is adjacent to a space in the seat portion of the base support that is located and dimensioned such that application of a force, onto the top side of the member at a location substantially within the boundaries of the unsupported area at the bottom side will cause the member to pivot/tilt into the space and lift above the support plane at a diagonally opposite side from the location where the force is applied so that it can be easily grasped and removed.

Systems and methods of reducing the likelihood of unfiltered fluid exiting a fluid filtration system. A fluid filtration system comprises a housing, a filtration chamber, a removeable filter cartridge contained within the chamber, and a removable chamber cap forming a boundary of the chamber. A method of assembling the filtration system comprises removably attaching the filter cartridge to the chamber cap and removably attaching the chamber cap to the housing to thereby form the hermetically sealed filtration chamber containing the filter cartridge.

A filtering funnel assembly has an outer body having a plurality of panels. A first one of the panels is joinable to a second one of the panels to define a funnel. Each of the plurality of panels including a top edge and a bottom edge, the top edges define a funnel inlet and the bottom edges define a funnel outlet. A liner is nestable within the funnel, the liner has a top portion forming an opening and a bottom portion. A portion of the liner is configured to attach to a portion of the funnel. The liner nested within the outer body enables a fluid to enter the fluid inlet of the funnel and the fluid inlet of the filter liner and to pass through the bottom portion of the filter liner and the fluid outlet of the funnel.

An apparatus having a bottom assembly for interfacing to connect the bottom assembly to a second structure, having a deformable element that, when sufficient force is applied via the process of attaching the bottom assembly to the second structure, and at an appropriate value of axial compression or pressure, passes from a stable state, through a rapid shape transformation to a second state via a regime of reduced resistance to deformation, creating a tactile or audible indication that the apparatus has been properly installed. The deformable element may be joined to the apparatus using a circumferential insertion ring by friction fit or spring fit, may be inserted inwardly of a sealing surface and may adhere magnetically to the second structure to facilitate installation.

Filter caps, filter assemblies, and filtration systems and methods.

During the process of compressing air, atmospheric air along with water vapor and airborne contaminants are ingested into the air compressor. Many of these compressors utilize oil for lubrication, sealing and cooling. A compressor system utilizes drain valves to remove the condensate that accumulates in the system which are typically located on the compressor, moisture separators, coalescing filters, receivers, dryers, and drip legs. While the drain valves successfully remove the condensate, this condensate is now contaminated with lubricant. The compressor system also includes a filter for the removal of lubricant from the condensed water so that the water can be discharged to sewer. The filter is arranged to house a series of vertically stacked filter cartridges, each cartridge structured to pass fluid flow to the other cartridge. The housing is connected to the filter cartridges via a variable length pipe extension dependent on the number of filter cartridges used in an application.

A closing and opening device for cartridge filter housings, including a first body and a second body, which move relative to each other, a sealing element between the first body and the second body and moving devices of the first body with respect to the second body; the moving devices are configured to perform a relative shift between the first body and the second body, moving them close and away, to switch from the first configuration where the first body and second body are located at a first distance so that the sealing element is in a resting position to the second configuration where the first body and second body are placed at a second distance, shorter than the first distance, so that the sealing element is compressed by the first body and by the second body.

The present invention discloses an improved multiple filtration cartridge assembly comprising filter cartridges with internal riser tubes mounted on a collection rail via rail couplers. Within this configuration, at least one internal riser tube contains a drain down orifice which corresponds to a matching drain down orifice on the rail coupler. The disclosed assembly increases the lifespan of the filter cartridges. Further, the multiple filtration cartridge assembly may be configured as a filtration mechanism within a variety of Structural Best Practice Management water filtration systems.
