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 filter, system and method is provided for filtering nanoparticles in a hot gas, namely particles <about 1 micron in a gas >about 200° C. and further particularly >about 450° C. including diesel exhaust. The filter includes filter media material composed of fibrous filter media having a plurality of fibers and granular filter media having a plurality of granules extending from the surfaces of the fibers. The filter is characterized by a permeability >about 3×10?12 m2 and an inertial resistance coefficient <about 1×106 m?1. The filter captures particles in the Most Penetrating Region (MPR). A filter system includes a nanoparticle filter in series with a diesel exhaust treatment element.

Abstract: A pressure gradient dosing system is provided for a fluid supply system. A flow passage has first and second pressure zones having a pressure gradient therebetween. An additive reservoir in an additive delivery system responds to the pressure gradient to release additive to the flow passage.

Abstract: A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally. molded seal is provided.

Abstract: Acid-neutralizing filter media includes filter media fibers in combination with a strong base of small particle size and high surface area attached to and immobilized on the filter media fibers, and methodology therefor.

Abstract: A filter includes first and second sheets of filter media, the second sheet being pleated and forming with the first sheet a plurality of axially extending flow channels having lateral cross-sectional shapes with two adjacent included angles each greater than 45° and less than 75°. Forming apparatus and methods are provided.

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 container (1) for releasing a chemical additive (7) in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing (3) having a hollow interior and an additive composition (7) comprising at least one fluid material-soluble additive. The additive (7) is held within the container (1) by a least one fluid material-permeable element (11) provided at or near an opening (13) in the casing (1) and is effective to provide for release of additive(s) (7) into the fluid material. Methods of releasing additives (7) into fluid material are also provided.
