Abstract: A gas turbine air intake system uses a filter element (42) having a seal member with radial projections and radial recesses. The seal member forms a seal with components (104) on the tube sheet (38) 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 (112), or alternatively, an additional filter cartridge.

Abstract: According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge (415) includes a seal arrangement (420) having radially directed seal surface (445a) with at least a first non-wavy or non- projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

Abstract: A filter element, for placement in a housing of a filter system, includes a filter medium pack and a seal arrangement having a seal and a seal carrier. The filter medium pack includes, for example, a pleated filter medium or a fluted filter medium. The seal carrier includes an axial side coupled to at least a portion of an axial face of the filter medium pack by a thermal welding manufacturing process. The coupling of the seal to the seal carrier is obtainable by manufacturing the seal arrangement with a multi-material injection molding manufacturing process. The present disclosure further relates to a method for manufacturing a filter element, the method including steps of thermal welding and multi-material injection molding.

Abstract: A filter element for insertion into a housing of a filter system. The filter element includes a filter medium pack and a seal receiver. The filter medium pack has an outer circumferential face extending between a first outer axial face and a second outer axial face, opposite the first outer axial face. The filter element further includes a seal receiver sealingly attached to the filter medium pack. The seal receiver includes a closed-loop surface suitable for receiving a removable circumferential seal member, and wherein the closed-loop surface forms a contour shape with single-fold rotational symmetry. A seal assembly including a filter element and a seal carrier is also presented.

Abstract: According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.
