Abstract

An air filter arrangement is disclosed. The air filter arrangement includes strips of media comprising fluted sheets secured to facing sheets and forming inlet and outlet flutes secured to one another in a stack. Media pack arrangements including such stacked media with peripheral, perimeter, housing seal arrangements are described. Also described are air cleaners including the filter cartridges. Methods of assembly and use are also provided. Also, systems of use are described.

Claims23

Dependent claims

An air filter cartridge comprising:

(a) a filter media pack having first and second opposite flow faces;
the filter media pack comprising a stacked construction of individual strips of filter media comprising fluted media secured to facing media to define inlet and outlet flow channels extending between the first and second, opposite, flow faces;
(i) the filter media pack being closed to passage of air therethrough, from the first flow face to the opposite second flow face, without filtering passage through the media;
(ii) the filter media pack having a configuration with four sides extending between the first and second opposite flow faces;
and,
(iii) the four sides defining first and second, opposite, sides;
and, third and fourth, opposite, sides;
and,
(b) a housing seal arrangement comprising a perimeter seal extending around the four sides of the media pack;
(i) the housing seal arrangement being positioned spaced from at least one of the first and second, opposite, flow faces;
(ii) the perimeter seal having a first section extending across a first one of the sides along a path not continuously parallel to a media pack edge between a corresponding side of the media pack and the second flow face;
(A) the first section extending across the first one of the sides at a first angle X1, to the media pack edge between the first side and the second flow face of at least 2°;
and,
(iii) the housing seal arrangement including a base and a pinch seal lip;
(A) the pinch seal lip being positioned on, and molded integral with, the base;
and,
(B) the base and pinch seal lip defining a trough between at least a portion of the pinch seal lip and the media pack.

(1) the first section extending across the first one of the side at a first angle X1, to the media pack edge between the first side and the second flow face of at least 2°;
and,
(C) the housing seal arrangement including a base and a pinch seal lip;
(1) the pinch seal lip being positioned on, and molded integral with, the base;
and,
(2) the base and pinch seal lip defining a trough between at least a portion of the pinch seal lip and the media pack.
