    摘要： An air filtration assembly has a box having a wall extending along a first axis and a second axis and a filtering cartridge insertable into the box and having at least two tubular filtering partitions extending along a filter axis and a plate group extending with respect to an imaginary development plane and having a first face having at least one sealing profile and a second face having at least two abutment profiles. The box has an accommodation region accommodating the plate group. The at least one sealing profile and/or the at least two abutment profiles are shaped or mutually positioned with respect to the imaginary development plane having vertical and longitudinal variable distances therefrom. The at least two tubular filtering partitions define a main extension row along the first or second axis. Two tubular filtering partitions of a same row and proximal to each other have respective filter axes mutually offset along the first and second axes.

    摘要： A filter element is mountable to a mast of a filter system having a threaded rod at a distal end thereof. The filter element includes cylindrical filter media, first and second end caps, and a seal washer. The media circumscribes a central axis. The first end cap is a first annular end cap and has a central opening configured for receiving the mast therethrough. The second end cap includes a seal washer opening defining a seal washer opening center that is located either concentric or non-concentric to the central axis of the media. The central opening of the first end cap is larger in dimension than the seal washer opening. The seal washer is receivable within the seal washer opening in at least a first orientation relative to the seal washer opening center. In the first orientation, a rod hole of the seal washer is non-concentric to the central axis.

    摘要： According to the present disclosure, air cleaner assemblies, components, features, and methods relating thereto, are described. These features, in part, relate to configuration of a preferred seal arrangement and seal surface of the cartridge. Particular arrangements are shown, in which: the filter cartridge includes a seal arrangement having a axial pinch seal surface with a projection/recess contour including at least one projection thereon; and, the cartridge includes a seal contour projection stabilizing portion at a location in perimeter alignment with the portion of the seal pinch arrangement including the first housing engagement projection. Additional features are included that relate to clean air separator section tubes of a precleaner arrangement secured to a cartridge. These features can be used in cartridges including features outlined above, or in alternative cartridges. Additional features of air cleaner arrangements and filter cartridges in accord with the above are described.

    摘要： Disclosed herein is a filter having a housing having first and second end surfaces and interior and exterior surfaces, a membrane disposed within the tubular housing, a first end cap sealed to the first end surface of the tubular housing and the first end surface of the membrane; a second end cap sealed to the second end surface of the tubular housing and the second end surface of the membrane; and a fluid channel formed in the interior surface of the housing in a helical pattern. The helical pattern has a helical pitch in an axial direction of the housing of less than or equal to about 60 mm.

    摘要： An air filtering system having: an air box, which has at least one inlet opening and at least one outlet opening; and an air filter, which is arranged inside the air box. The air box has two opposite twin mounting openings, which are obtained in two parallel and opposite walls of the air box and are shaped to allow the air filter to be inserted and removed through each one of them. Two removable doors are provided, each having an outer panel configured to overlap a respective mounting opening to close the mounting opening and two inner appendages, which project perpendicularly from two opposite ends of the outer panel so as to be arranged on the two opposite sides of the air filter, when the door is coupled to the respective mounting opening.
