Publication number: 20220362697Abstract: Articles such as filter media, which include dendrimers and/or other components, are provided. The filter media may further include a water repellant (e.g., a fluorinated species) to impart desirable properties to the media such as high water repellency. The filter media may also have a high efficiency as a function of pressure drop (i.e., high gamma values). In some embodiments, the filter media includes a fiber web which may be formed of various components such as glass fibers. The fiber web can also include additional components such as synthetic fibers, binder components, as well as other additives. The media may be incorporated into a variety of filter element products.Type: ApplicationFiled: May 14, 2021Publication date: November 17, 2022Applicant: Hollingsworth & Vose CompanyInventors: David F.

Publication number: 20160166962Abstract: Filter media suitable for various applications and related components, systems, and methods associated therewith are described. The filter media may include a composite filter media structure having a substrate and at least one fine fiber layer. The fine fiber layer may include a plurality of glass fibers having an average fiber diameter of less than 2 microns; or, at least 70% by weight of the glass fibers within the fine fiber layer has a fiber diameter of less than 2 microns. The fine fiber layer may further include a fluorochemical composition, an organosilicon composition and may optionally include a binder composition that comprises less than 2% by weight of the fine fiber layer. The filter media may exhibit both a relatively high gamma and favorable mechanical properties. The filter media may be produced by forming a substrate on the surface of a wire in a wet laid process, and forming a fine fiber layer on the substrate while the substrate is on the wire.Type: ApplicationFiled: December 11, 2015Publication date: June 16, 2016Applicant: Hollingsworth & Vose CompanyInventors: David F. Sealey, Sudhakar Jaganathan, Randall B. Keisler, David Vallery
