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 with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. 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.

Abstract: A filter element of a liquid filter has a filter medium surrounding an element interior with a radially inner and a radially outer circumferential side as inflow side for raw fluid and outflow side for clean fluid, respectively. A sealing element arrangement of a sealing device is arranged at a filter medium end face. The sealing device seals a fluid connection between a liquid discharge line of a filter housing and the raw fluid side or clean fluid side of the filter element. The sealing element arrangement has radially inner and radially outer sealing elements extending circumferentially relative to the element axis. The radially outer and radially inner sealing elements are concave, viewed from a pressure-loadable side of the filter element. The radially outer sealing element has a radially outwardly or inwardly extending sealing lip; the radially inner sealing element has a radially inwardly or outwardly extending sealing lip.

Abstract: A filter of a filter device has a filter housing with a connecting side provided with a connecting element for detachably connecting the filter to a filter head of the filter device by a rotational and/or insertion movement relative to an imaginary connecting axis of filter and filter head. The filter housing has an inlet for fluid to be purified and an outlet for purified fluid. An outer seal seals a connection of the filter with the filter head relative to the environment. The outer seal is circumferentially continuous relative to the connecting axis. A closure element is provided to close off, when the filter is connected to the filter head, a fluid drain in the filter head provided for draining fluid when removing the filter from the filter head. The outer seal is acting sealingly at least in radial direction relative to the connecting axis.

Abstract: A flow cap may include an outer ring, an inner ring, an inlet portion, and an outlet portion. The inlet portion may include first portions of the outer and inner rings, and a plurality of arms extending between the first portions of the outer and inner rings, wherein the arms at least partially define an inlet aperture configured to provide flow communication between an inlet port of a filter base and an interior portion of a filter element. The outlet portion may include second portions of the outer and inner rings, and a plate including an outlet aperture providing flow communication between an outlet port of the filter base and an exterior portion of the filter element. The outlet portion may also include a wall, wherein the plate and the wall prevent flow communication between fluid entering the inlet portion and fluid entering the outlet portion.

Abstract: A vacuum filter device comprising a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element and the sealing element is maintained in place by a compression element formed of a ring. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place under a compression seal. Optionally a port in the compression element is formed to align with the vent of the device. Further, an alignment feature on the compression element ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.
