AIR FILTER ARRANGEMENTS; ASSEMBLIES; AND, METHODS

摘要

Air cleaner assemblies and components therefor are described. An example first or main filter cartridge is described which includes a media pack comprising fluted material secured to facing sheets. The media pack defines opposite inlet and outlet flow faces, with flutes extending in a direction therebetween. The cartridge defines a closed end, spaced from, but in overlap with, the outlet end face of the media pack.

主权项

1. An air filter cartridge removably installable in a housing of an air cleaner; the air filter cartridge comprising:
(a) a media pack comprising fluted media secured to facing media and defining opposite inlet and outlet flow faces;
(i) the media pack being closed to passage of air therethrough without filtering passage through media therein; (b) a member on the media pack defining a filter cartridge clean air volume adjacent the outlet flow face of the media pack;
(i) the member on the media pack including an air flow outlet in communication with the filter cartridge clean air volume and oriented for air flow therethrough in a direction generally orthogonal to a flow direction between inlet and outlet flow faces; and, (c) a housing radial seal positioned on the member that is on the media pack.
