Abstract: Pulse jet air cleaner systems, components and methods are described. The features relate to air cleaner housings that include a cartridge receiving section. Features described relate to a possible two-stage construction, a possible pulse jet accumulator section, pulse jet equipment for cleaning a filter cartridge positioned within the air cleaner; possible evacuation valve arrangements for projection of dust from the air cleaners; and other example features. Methods of assembly and use are also provided.

Abstract: Principles, techniques and configurations applicable in air cleaner arrangements and filter cartridges therefore, are described. In general the filter cartridge includes an axial pivot arrangement, for pivoting the filter cartridge in place, when mounted in an air cleaner for use. The air cleaner may include a base pivot, for engagement with the pivot projection on the filter cartridge. Methods of assembly, installation and use are described.

Abstract: Methods, techniques, and constructions are provided for use to apply an evacuation valve arrangement on an air cleaner assembly that is configured for pulse jet operation. An example evacuation valve arrangement is provided which comprises a valve member in the form of a sleeve that extends completely around a sidewall portion of an air cleaner housing of a pulse jet air cleaner. Examples are depicted in which the sidewall portion can comprise: a portion of a housing sidewall section that surrounds an installed filter cartridge, in use; a portion of an access cover; or, a drop tube secured to a portion of the housing, for example either on an access cover or on another portion of a housing. Specific features and alternatives are described. Also, methods of assembly and operation are described.

Abstract: An air cleaner arrangement or assembly is provided. The air cleaner arrangement includes a serviceable filter cartridge. The air cleaner assembly also includes an arrangement for positioning the filter cartridge into a preferred, sealing, orientation and for securing the filter cartridge in that location. Preferred serviceable filter cartridges are provided, as well as methods of assembly and use.

Abstract: Filter arrangements include a barrier media in the form of fluted media treated with a deposit of fine fibers. The media is particularly advantageous in high temperature (greater than 140 to 240° F.) systems. Such systems may include engine systems, gas turbine systems, and fuel cell systems. Filter arrangements may take the form of media packs having a circular cross-section or a racetrack shaped cross-section, or media packs formed in a panel configuration.

Abstract: A V-pack filter includes a frame construction having a first frame structure and a second frame structure. The V-pack filter also includes first and second panel sections mounted in extension between the first and second frame structures. The first panel section has first and second ends. The second panel section has third and fourth ends. The first and third ends have a first distance therebetween while the second and fourth ends have a second distance therebetween. The second distance is generally greater than the first distance. The first and second panel sections and the second frame structure define an air flow aperture. A seal arrangement circumscribes the air flow aperture and projects outwardly from the second frame structure. The first frame structure defines a first receiver indent. Assemblies and methods are also included.
