Air cleaner and preferred components for an air cleaner are provided. In certain arrangements, a band is mounted to the media pack, surrounding the media. Also, the cartridge is non-circular and includes a seal thereon.

Filter arrangements; housings; assemblies; and, methods

Air cleaner and preferred components for an air cleaner are provided. In certain arrangements, a band is permanently mounted to the media pack, surrounding the media. Also, the cartridge is non-circular and includes a radial seal thereon.

Filter arrangements; housing; assemblies; and, methods

An air cleaner and preferred components for an air cleaner are provided. In one arrangement, the air cleaner includes a band or cassette component, configured for removably receiving a z-filter media pack therein, during use. In another arrangement, the band is permanently mounted of the media pack. Air cleaner arrangements configured for use of the cassette or band therewith included an arrangement with a central housing section for receipt of the main filter cartridge and cassette, and which has thereon a mounting arrangement with 3 mountable sides. Preferred precleaner arrangements and outlet tube arrangements can be secured to the center housing section.

A liquid filter assembly comprises a filter cartridge and a filter head in fluid communication with the filter housing. A filter media construction is positioned within the housing. The filter media construction, in combination with the housing, defines an unfiltered liquid volume and a filtered liquid volume. The filter head includes an inlet for conveying liquid to the unfiltered liquid volume, a first outlet for conveying liquid from the filtered liquid volume, and a second outlet. A first valve assembly is provided which is constructed and arranged to selectively permit passage of liquid from the unfiltered liquid volume through the second outlet, in response to a first selected liquid pressure level within the unfiltered liquid volume. A second valve assembly is disposed within the filter head and is constructed and arranged to selectively permit passage of liquid from the filtered liquid volume through the second outlet in response to a second selected liquid pressure level within the filtered liquid volume.

Filter head and liquid filter assembly with valve arrangements

The filter head and filter housing define a liquid flow inlet path, a first liquid flow outlet path, and a second liquid flow outlet path. A filter media construction is positioned within the housing. The filter media construction, in combination with the housing, defines an unfiltered liquid volume, and a filtered liquid volume. A first liquid flow inlet path directs liquid from the liquid flow inlet to the unfiltered liquid volume. A first liquid flow outlet path directs liquid flow from the filtered liquid volume to the first liquid flow outlet. A second liquid flow outlet path directs liquid flow from the filtered liquid volume to the second liquid flow outlet. A first valve assembly selectively opens the second liquid flow path to passage of liquid therethrough in response to a first selected liquid pressure level within the filtered liquid volume. A second valve assembly comprises a first bypass valve assembly, and selectively directs fluid flow from the unfiltered liquid volume to the second liquid flow outlet, in response to a second selected liquid pressure level within the unfiltered liquid volume.
