    摘要: Filter media comprising fine staple fibers and related components, systems, and methods associated therewith are provided. In some embodiments, a filter media may include a layer (e.g., a wet laid layer) comprising polymeric staple fibers having a relatively small average diameter (e.g., less than or equal to about 1 micron). The polymeric staple fiber layer may be designed to impart desirable properties to the filter media, such as a high particulate efficiency and/or fluid separation efficiency, while having relatively minimal or no adverse effects on one or more properties of the filter media that are important for a given application. The filter media, described herein, may be particularly well-suited for a variety of applications.

    摘要: The present invention relates to a filter unit for filtering a compressed gas contaminated with oil, in particular compressed air, wherein the filter unit contains a coalescence filter for coalescing the contaminant contained in the compressed gas, in particular oil. The coalescence filter comprises a housing with a gas supply for supplying the gas to a primary coalescence medium disposed in the housing, the gas flowing in a flow direction, wherein the primary coalescence medium contains at least one first layer of a first porous coalescence medium and a second layer of a second porous coalescence medium adjacent to the first layer, wherein the primary coalescence medium has a total thickness of at least 3.5 mm, measured at a pressure of 2 N/cm2.

    摘要: Surface modified filter media, including surface modified filter media having enhanced performance characteristics, are provided. In some embodiments, a filter media may comprise two or more layers designed to enhance fluid separation efficiency. One or more of the layers may have at least a portion of a surface that is modified to alter and/or enhance the wettability of the surface with respect to a particular fluid. In certain embodiments involving a filter media including more than one surface modified layer, at least one surface modified layer may have a greater air permeability and/or mean flow pore size than that of another surface modified layer. Such a configuration of layers may result in the media having enhanced fluid separation properties compared to filter media that do not include such modified layers or configuration of layers, all other factors being equal. The filter media may be well-suited for a variety of applications, including filtering fuel, air, and lube oil.
