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&#xb0; and less than 75&#xb0;. Forming apparatus and methods are provided.

Filter and forming system

A filter, system and method is provided for filtering nanoparticles in a hot gas, namely particles &#x3c;about 1 micron in a gas &#x3e;about 200&#xb0; C. and further particularly &#x3e;about 450&#xb0; 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 &#x3e;about 3&#xd7;10mand an inertial resistance coefficient &#x3c;about 1&#xd7;10m. 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.

High temperature nanofilter, system and method

An exhaust aftertreatment combined filter and catalytic converter has a plurality of flow channels each having both: a) a flow-through channel catalytically reacting with the exhaust; and b) a wall-flow channel trapping particulate such as soot. A filter is also provided.

Catalyst and filter combination

A coating system (), winding system (), finishing system () and manufacturing system (FIGS.) is provided for spiral-wound fluted filter media ().

Filter coating, winding, finishing and manufacturing system

A green uncured pre-form ( ) for an exhaust aftertreatment filter includes first and second sheets ( and ) of regenerable filter material, 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 ( and and ) each greater than 45&deg; and less than 75&deg; and having wall segments ( and and ) with a thickness less than 0.8 mm, a porosity greater than 80%, and an extension height (b) between pleat tips less than 10 mm. Forming apparatus ( ) and methods are provided.
