A reductant storage system for an internal combustion engine system includes a storage container having a bottom wall, a top wall opposite the bottom wall, an opening extending through the top wall, and a reservoir formed by a hollow interior of the storage container and a filter assembly. The filter assembly extends through the opening and include a filtering material and a gasket integrally formed with the filtering material. The gasket includes a proximal flange that is larger than the opening and including a sealing surface in sealing contact with the storage container.

A reductant storage system for an internal combustion engine system includes a storage container having a bottom wall, a top wall opposite the bottom wall, an opening extending through the top wall, and a reservoir formed by a hollow interior of the storage container; a filter assembly; and a header assembly. The filter assembly extends through the opening and is configured to seal the opening and includes a filtering material. The header assembly extends through the opening and inside the filter assembly. The header assembly includes: (i) a first sensor configured to measure a quality of the reductant contained within the filter assembly and (ii) a second sensor configured to measure a level of the reductant contained within the filter assembly.

An adaptor device for retrofitting in a pool filter housing is disclosed, where the pool filter housing has a conventional cylindrical concentric filter. The adaptor device allows the pool filter to be retrofitted with a plurality of filter elements, thereby improving its filtering efficiency.

An apparatus facilitates multiple paths or circuits through an engine and remote housing for an oil filter. The apparatus includes a first oil filter chamber housing a first oil filter, a second oil filter chamber housing a second oil filter, a first output of the remote housing configured to provide a path from the first oil filter chamber housing to bearings of an engine, a second output of the remote housing configured to provide a path from the second oil filter chamber housing to a sump of the engine, and an input of the remote housing configured to provide a path from an oil pump of the engine to the first oil filter chamber housing.

A tank screen (10) having at least one contact region or contact area (14) for positioning the tank screen relative to a tank inlet, a solid wall (16) having a portion extending above the at least one contact area or contact region (14), and a mesh screen (18) for filtering leaves from water entering the rainwater tank, the mesh screen (18)comprising a mesh side wall (20) that has an upper region located above the at least one contact area or contact region (14), the at least the upper region of the mesh sidewall (20) being at least partly enclosed by the solid sidewall (16).

A method including the steps of moving fluid through an inlet into a vessel, the vessel being at atmospheric pressure and having at least one side wall and a bottom wall forming an internal chamber within the vessel. The method further includes moving the fluid into and through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft.sup.2), and moving the fluid processed by the filtration unit to an outlet and out of the vessel.

A filter device allows avoiding liquid and dust before filtration to flow out to a tank during replacement of a filter element. A case includes a first tubular portion and a second tubular portion positioned with a lower side of the first tubular portion. The second tubular portion has a diameter smaller than that of the first tubular portion. In a state where the filter element is provided inside the case, a tubular portion of the filter element abuts on the second tubular portion. A part abutting on the second tubular portion of the tubular portion is absent of a hole. A part without abutment on the second tubular portion of the tubular portion has a plurality of holes.

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 base filter for a diesel exhaust fluid (DEF) filter of a header assembly in a fluid reservoir is disclosed may include first and second semi-cylindrical holder portions having a semi-cylindrical walls concluding at abutment surfaces that face and engage when the base filter is assembled. The semi-cylindrical holder portions have one or more mounting tabs extending inward from inner surfaces of the semi-cylindrical walls. The header assembly may include a header with a cylindrical header boss having mounting recess defined therein. The mounting tabs may be circumferentially spaced about the semi-cylindrical walls to align with and be inserted into the mounting recesses of the header boss the base filter is assembled on the cylindrical header boss. Fasteners may be inserted through fastener bosses of the semi-cylindrical holder portions and into fastener bores of the header boss to hold the semi-cylindrical holder portions together and on the header.

A liquid surface height inside a tank is allowed to be confirmed while blow-back of a liquid is reduced. A strainer body having a substantially bottomed tubular shape has a substantially D shape when viewed in a longitudinal direction. A bottom surface of the strainer body has a shape in which a part of a conical shape is cut away, and a top of the substantially conical shape overlaps with a notched portion notched to form the substantially D shape. The bottom surface protrudes toward an opening of the strainer body. A rod is provided adjacent to the notched portion of the strainer body, and a float is provided on a lower end of the rod.
