摘要: A filter is composed of filter media having the following characteristics in combination: a) the filter media has a greater affinity for the filtered fluid than for contaminants in the fluid, and wherein the work of adhesion between the filter media and the contaminants is less than the work of adhesion between the filter media and fluid, and wherein the filter media is preferentially wetted by the fluid relative to the contaminants; b) the filter media is composed of fibers having a defined surface area ratio facilitating fewer attachment sites for contaminants, and, in the case of cleanable reusable filters, facilitating cleansing backwash of the cleanable reusable filter by cleansing fluid along a reverse flow backflush path; c) the filter media has a thickness of 0.025 to 0.075 inch, 0.7 to 2.0 millimeters; d) the face area of the filter media is maximized by pleating the filter media and forming the pleated filter media into an annulus having an inner circumference and an outer circumference and having at least five pleats per inch along the inner circumference; e) the filter media is optionally provided with both upstream and downstream support layers preventing collapse of the thin surface filter media during both filtration and backwash, the support layers being pleated annular screens sandwiching the pleated filter media therebetween, the inner portions of the pleats of the downstream support layer screen adjacent the inner circumference preventing blinding.

摘要: A filter housing (14) has a first inlet (16) for receiving a first fluid such as oil from a machine such as an internal combustion engine (12), a first outlet (20) returning the first fluid to the machine, a second inlet (24) selectively receiving a second fluid from a source of cleaning fluid (28), and a second outlet (30) exhausting the second fluid. The filter housing has a first flow path therethrough from the first inlet through a filter element (40) in one direction to the first outlet, and a second flow path therethrough from the second inlet then through the filter element in the opposite direction then to the second outlet. The first and second inlets and the first and second outlets are all provided at the same axial end of the housing, for modularity. First and second common flow channels (58 and 68) in the housing each carry the first and second fluids in opposite directions. First and second valves (84 and 86) in the housing enable switching between filtration and cleaning modes.

摘要: Disclosed are modular filter-in-filter elements, namely an outer filter element and an inner filter element which may be assembled to form a filter cartridge for use in separation methods and systems. The outer filter element typically functions as a coalescing element and the inner element typically functions as a particulate filter element. The disclosed filter cartridges may be structured for separating water from a hydrocarbon-based liquid fuel as the fuel moves through the cartridge from outside to inside.

摘要: A reusable oil filter adapted to filter oil used in an engine includes a housing operatively connected to the engine, filter media disposed within the housing, a singular backwashing inlet operatively connected on the housing and an oil drain operatively connected with the housing. Pressurized air delivered through the backwashing inlet forces filtered oil to backflow through the filter media displacing contaminated oil from the filter media and creates an air-oil foam for further cleaning the filter media while the housing remains connected to the engine.
