摘要： A composite media includes a stack with 20 or more layers, each layer including a substrate with a first major surface and an opposing second major surface; and a fiber layer deposited onto the first major surface of the substrate and including polymeric fibers with a diameter of 100 nm to 1.5 μm. Each fiber layer independently has a thickness of 5 μm to 100 μm, and each layer independently has a pore size of 0.1 μm to 10 μm. A filter may include a housing and the composite media disposed within the housing. The filter may be a syringe filter.

摘要： A filter device for filtering fluid particularly an aqueous urea solution, includes a filter housing (1), a filter element (11) and a compensating element (31) for compensating fluctuations in the pressure and/or volume of the fluid. At least one elastically-flexible membrane (31) serves as the compensating element. The membrane wall of of the membrane is held in a retaining part (35) and maintains a separation between the fluid and a compressible filling medium such as a working gas.

摘要： A fluid filter removal device includes a fluid catch configured to circumscribe an outer surface of a fluid filter, a filter spacer configured to maintain a minimum separation between the outer surface of the fluid filter and an inner surface of the fluid catch when at least a portion of the fluid filter is circumscribed by the fluid catch, and a fluid filter sheath, fixed and hydraulically sealed to the fluid catch proximate the filter exit end of the fluid catch. The fluid filter removal device provides a device and method for removal of oil or fuel filters, and to contain contaminated fluids, on automotive, heavy and other types of equipment to eliminate contamination to the environment as well as contamination to vehicles and users changing a fluid filter.

摘要： A liquid filter insert for a liquid filter has a prefilter element and a main filter element connected to the prefilter element. Prefilter element and main filter element are arranged on top of each other in an axial direction relative to a longitudinal axis of the liquid filter insert. A connection provides a flow path for liquid to flow from the prefilter element to the main filter element. The prefilter element is provided with a water separation unit and is further provided with a filter medium. The water separation unit is arranged between the filter medium of the prefilter element and the connection such that the liquid, after passing through the filter medium, flows through the water separation unit into the connection. The water separation unit has a water discharge channel for water separated from the liquid that extends axially at least partially through the main filter element.

摘要： To move a filter along a manifold assembly the filter may be seated on a moveable shuttle assembly. Seating the filter on the shuttle assembly may include mating a key portion on the filter with a key portion on the shuttle assembly, each key portion corresponding to a filtration characteristic of the filter. The shuttle assembly and the seated filter may then be moved between a first position, wherein the key portions of the filter and the shuttle assembly are mated to one another and first and second fittings of the filter are spaced from first and second fittings of the manifold assembly, and a second position, wherein the key portions of the filter and the shuttle assembly are mated to one another and the first and second fittings of the filter sealingly engage the first and second fittings of the manifold assembly.

摘要： A filter has first and second fittings, a permeable filter medium, and a housing. The housing defines a fluid flow path within the housing between the first and second fittings, and the permeable filter medium is arranged in the fluid flow path to remove one or more substances from a fluid flowing along the fluid flow path. A reservoir is positioned in an upper region of the housing and includes a wall surrounding the first and second fittings of the filter. Each of the fittings has a topmost portion and the wall of the reservoir has a topmost portion, the topmost portion of each filter fitting being at or below the topmost portion of the reservoir wall. A filter arrangement may include a filter and a manifold assembly having first and second fittings which may be sealingly coupled to or uncoupled from the first and second fittings of the filter.
