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.

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： Filter media, including those suitable for fuel and/or hydraulic applications, and related components, systems, and methods associated therewith are provided. In some embodiments, a filter media may include a non-woven layer comprising blend of glass fibers and polymeric staple fibers. The polymeric staple fibers may have a relatively small diameter. The non-woven layer comprising the fiber may have desirable properties such as one or more of a low micron rating for beta efficiency, high dust holding capacity, and/or a low resistance to fluid flow. In certain embodiments, the filter media may include two or more layers, at least one of the layers including a non-woven layer comprising the fiber blend. In some such cases, the filter media may include one or more layers that serve to enhance the overall properties of the filter media.
