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. 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.

Dependent claims

An air filter cartridge comprising:

(a) a filter media pack having an air inlet flow end and an opposite air outlet flow end, wherein the filter media pack comprises a first pair of opposite sides extending between the air inlet flow end and the air outlet flow end, and a second pair of opposite sides extending between the air inlet flow end and the air outlet flow end;
wherein:
(i) the filter media pack extends over a distance of at least 80 mm in a direction between the air inlet flow end and the air outlet flow end;
and
(ii) the first pair of opposite sides of the filter media pack each have a straight section that extends over a distance of at least 40 mm in a direction along a periphery of the filter media pack;
(b) a first arrangement comprising:
(i) a first body portion extending around the filter media pack first pair of opposite sides and the filter media pack second pair of opposite sides;
and
(ii) a seal support extending away from the first body portion;
(c) a second arrangement comprising:
(i) a second body portion covering at least a portion of the filter media pack first pair of opposite sides;
(d) the first arrangement and the second arrangement are adhered together;
