Filter cartridge arrangements, features, and methods of construction are described. Also described are filter assemblies having the filter cartridge installed therein as a removable service component. The filter cartridge generally comprises a media pack having an end with an end cap positioned thereon. The end cap includes an end cap section, a seal support and a seal member secured thereto. Methods of assembly and use are described.

Also described are filter assemblies having the filter cartridge installed therein as a removable service component. The filter cartridge generally comprises a media pack having an end with an end piece positioned thereon. The end piece includes an end cap section and a seal support, defining a seal recess. A seal member is secured within the seal recess. Methods of assembly and use are described.

Air cleaner assemblies and serviceable filter cartridges therefor are described. Example filter cartridges described which include a first end cap with a air flow aperture therethrough, having an outer axial surface and axial seal ring thereon. Example arrangements are provided with air flow inlet tube section defining the aperture through the first end cap. Also, water seal arrangements, typically positioned radially inwardly from the air seal arrangement, are described.

Filter cartridge

An air filter element includes structure for supporting a secondary air filter element mounted within it, such as a safety element. In certain arrangements, the air filter element includes a media pack having first and second ends and defining an open filter interior. A first open end cap is positioned on the media pack first end. A second closed end cap is positioned on the media pack second end. The spacer construction has attachment structure and positioning structure. The attachment structure secures the spacer arrangement within the open filter interior, and the positioning structure extends from the attachment structure. In one illustrated embodiment, the spacer construction includes an insert embedded within the second closed end cap. In one illustration, the insert has a circular disk with feet and a centrally extending post with a fin arrangement.
