A gas turbine air intake system uses a filter element having a seal member with radial projections and radial recesses. The seal member forms a seal with components on the tube sheet of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover, or alternatively, an additional filter cartridge.

Filter element, systems, and methods

An air filter cartridge for use with an air cleaner assembly is provided. A variety of features for the air filter cartridge are characterized. An example air filter cartridge is depicted, which includes opposite flow faces. A preform secured to the media pack, with a seal member is described.

Air filter assembly; components thereof; and, methods

An air filter cartridge arrangement, an air cleaner assembly, and components therefor, are provided. The air filter cartridge generally has perimeter shape with an arched side. The filter cartridge may include a media pack comprising strips of single facer material, each strip comprising fluted sheet secured to a facing sheet. In an example depicted, arch-shaped sections of single facer material are nested within one another, to form media pack having a perimeter D-shape. An air cleaner assembly configured for receipt of filter cartridge is described. A particular assembly, convenient for mounting on the cowl, cowling or engine cover of an over-the-highway truck, is provided.
