An oil filter assembly for a differential housing, including a filter housing for releasably mounting in a drive axle housing and defining an internal volume for containing oil to be filtered, a mounting arrangement for releasably securing the filter assembly to a drive axle housing, and a filter element for filtering particulate contaminants from oil in a drive axle. The filter housing includes an inlet on an upper portion thereof and an outlet on a lower portion thereof to define an flow path therethrough, and wherein the filter element is located downstream of the inlet.

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.

Apparatus that makes it possible to prefill spin-on filter cartridges by allowing users to easily pour fluid only into the filter cartridge input port holes. Particularly useful for applications where introducing contaminants downstream of the filter can be detrimental to the system the filter protects.

The present disclosure relates generally to alternating tangential flow (ATF) perfusion pumping methods, including novel methods for generating positive and negative pressure at the point of use, and more particularly, to apparatuses, systems and methods for use of the same.

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.

Methods of filtering a liquid feed are disclosed. In one version, the method comprises passing a liquid feed through a single pass tangential flow filtration (SPTFF) system and recovering the retentate and permeate from the system in separate containers without recirculation through the SPTFF system. In another version, the method of filtering a liquid feed, comprises passing a liquid feed through a tangential flow filtration (TFF) system, recovering permeate and a portion of the retentate from the system in separate containers without recirculation through the TFF system, and recirculating the remainder of the retentate through the TFF system at least once. The methods can be performed using an SPTFF or a TFF system that comprises manifold segments to serialize the flow path of the feed and retentate without requiring diverter plates.

There is provided a filter for filtering particles in a container of fluid. The filter comprises a flow director comprising a hub, a plurality of radial blades extending from the hub and a plurality of vanes concentric about the hub. The blades and the vanes intersect to form a grid which collectively define a plurality of openings, each opening extending between a first face and a second face, where a cross-sectional area of each opening decreases from the first face to the second face. The filter further includes a skirt coupled to the perimeter of the flow director for maintaining the flow director in spaced relation from a bottom of the container. The decrease in cross-sectional area of the openings in the grid helps to prevent particles from travelling from a position below the flow director to a position above the flow director.

A dewatering unit in the form of a railcar having bogies thereon to move the unit on rail tracks. The dewatering unit has first and second ends, first and second sides, and a bottom that bound and define an interior chamber. A conveyor is provided in the interior chamber and screens are located in the bottom and first and second sides. A grizzly is located below an opening in the unit's top and above the conveyor. Stabilizing assemblies are deployed to contact the ground and lift some weight off of the bogies prior to loading. A solid material/liquid mixture is dropped through the opening and onto the grizzly which partially fractures the solid material. Further fracturing is undertaken by conveyor drag bars and crushers located adjacent the conveyor. Liquid drains from the unit through the screens. The dewatered solid material is lifted out of the unit by the conveyor.
