Abstract: A filter media pack with pleat folds, pleat panels and a plurality of glue bead sections is provided. The glue bead sections provide increased rigidity, dimensional stability and maintain spacing between adjacent pleat panels. Methods of manufacturing the filter media packs are provided. Filter elements including the filter media packs are contemplated.

Abstract: A filter element configured to be mounted to tube sheet openings of different diameters is provided. The filter element includes a seal member that can accommodate tube sheet openings of different diameters. Methods of mounting a plurality of identical filter elements to tube sheets having different tube sheet opening diameters is provided.

Abstract: A filter media is provided. The filter media has a blend of filter media fibers, including oxidized polyacrylonitrile (OPAN) fibers and fibers of at least one other polymer, such that the OPAN fibers comprise between 30% and 95% by weight of the blend. A filter element incorporating the filter media is also provided. A method of using the filter element is provided as well. Also provided is a method of manufacturing the filter media. The filter media has applicability for filtering air in such acidic environments as a cement factory, lime kiln, asphalt process, rock dust application, and coal fired boilers.

Abstract: The present invention is directed to systems and methods for improving the water management of exterior walls clad with panel siding. The present invention improves on prior art wall designs by directing water on the exterior surface of a building away from areas which are vulnerable to water penetration, such as joints between panels, joints between trim components, and locations where fasteners are driven from the exterior. The water management system generally comprises a vertical batten assembly, and in certain embodiments a horizontal joint cover. The water management system is designed to be installed on an outer surface of the exterior wall panels. Thus, the system may be installed without removing and replacing existing siding or covering panels with an entirely new layer of siding. The present invention may also be used on new panel siding installations as a lower cost alternative to other siding systems.
