Abstract: High performance filter media and manufacturing methodology provides nanofibers of diameter less than 1 ?m incorporated and processed into internal structure of a filter medium dominantly composed of coarse fibers of diameter greater than 1 ?m, to change the internal media structure.

Abstract: A disposable, spin-on fluid filter is constructed and arranged to mount onto a base that is configured with a threaded mounting shaft. The base provides a fluid inlet flow to the filter and a fluid exit path from the filter. The filter construction includes a housing canister having a closed end and an opposite, open end and a fluid filtering media positioned within the housing canister. A mounting post is formed as part of the closed first end of the housing canister. The mounting post is constructed and arranged for assembly to the threaded mounting shaft of the base. The design focuses on the elimination of any nutplate and on repositioning the location where the fluid filter is connected to the head to the closed end of the canister.

Abstract: A disposable, spin-on fluid filter for mounting to a fluid-directing head includes a molded housing having a closed base and a sidewall defining a hollow cavity. Filtering media is positioned within the hollow cavity and a nutplate is joined to the housing so as to enclose the filtering media. The nutplate includes a plurality of inlet flow openings and a lobed sleeve extending into the filtering media. An endplate is joined to the filtering media including a flange portion and a sleeve portion. The fluid filter includes an elastomeric valve having a first portion positioned between the flange portion and the inlet flow openings and a second portion positioned between the sleeve portion and the lobed sleeve. The valve provides an anti-drain back capability and in cooperation with the lobed sleeve provides a filtering media by-pass capability.
