Air cleaner assemblies and methods of use
A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.
1. A filter cartridge for insertion into a housing for an air cleaner assembly, the filter cartridge comprising:
a) a media pack extending along a longitudinal axis between opposite first and second flow ends, the media pack having opposite first and second long sides and having opposite first and second short sides;
b) a seal member presenting a seal surface facing in a radial direction for sealing against a housing surface facing in a radial inward direction; and
c) a first radially facing contact surface located along the media pack first long side and a second radially facing contact surface located along the media pack second long side, the first and second radially facing contact surfaces being separate from the seal member and located proximate the seal member and configured for engaging with the housing to constrain deflection of the housing in a radial direction away from the seal member.
2. The filter cartridge of claim 1 , wherein the first and second radially facing contact surfaces are radially inward facing contact surfaces.
3. The filter cartridge of claim 1 , wherein the seal surface deviates in an axial direction at a location along the media pack first and second short sides.
4. The filter cartridge of claim 1 , further comprising a handle, wherein the handle and the seal member are located proximate a common end of the filter cartridge.
5. The filter cartridge of claim 1 , wherein the first and second radially facing contact surfaces are located axially between the media pack first and second flow ends.
6. The filter cartridge of claim 1 , further comprising a shell at least partially surrounding the filter cartridge, wherein the first and second radially facing contact surfaces are formed as part of the shell.
7. The filter cartridge of claim 6 , wherein the first and second radially facing contact surfaces are formed as part of an opening or cutout in a portion of the shell.
8. The filter cartridge of claim 1 , wherein at least one of the first and second radially facing contact surfaces is located within a middle third of a length of the first and second long sides of the media pack.
9. The filter cartridge of claim 1 , wherein the seal member and the first and second radially facing contact surfaces are located proximate the media pack first flow end.
10. A filter cartridge for insertion into a housing for an air cleaner assembly, the filter cartridge comprising:
a) a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack having opposite first and second long sides and having opposite first and second short sides;
b) a seal member presenting a seal surface for sealing against a housing surface, the seal member being located proximate a first end of the filter cartridge;
c) a handle member located proximate the first end of the filter cartridge;
d) a first radially facing contact surface located along the media pack first long side and a second radially facing contact surface located along the media pack second long side, the first and second radially facing contact surfaces being located proximate the first end of the filter cartridge and configured for engaging with the housing to constrain deflection of the housing in a radial direction away from the seal member; and
e) a shell at least partially surrounding the media pack, wherein the first and second radially facing contact surfaces are formed as part of the shell.
11. The filter cartridge of claim 10 , wherein the seal surface faces in a radial outward direction.
12. The filter cartridge of claim 10 , wherein the seal surface deviates in an axial direction at a location along the media pack first and second short sides.
13. The filter cartridge of claim 10 , wherein the seal surface faces in an axial direction.
14. A filter cartridge for insertion into a housing of an air cleaner assembly, the filter cartridge comprising:
a) a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack having opposite first and second long sides and having opposite first and second short sides;
b) a seal member presenting a seal surface facing in a radial outward direction for sealing against a housing surface facing in a radial inward direction, the seal surface deviating in an axial direction at a location along the media pack first and second short sides; and
c) a first radially facing contact surface located along the media pack first long side and a second radially facing contact surface located along the media pack second long side, the first and second radially facing contact surfaces being located proximate the seal member and configured for engaging with the housing to constrain deflection of the housing in a radial direction away from the seal member.
15. The filter cartridge of claim 14 , further comprising a handle member located proximate a first end of the filter cartridge.
16. The filter cartridge of claim 14 , wherein the seal member is located proximate a first end of the filter cartridge.
17. The filter cartridge of claim 14 , further comprising a shell at least partially surrounding the filter cartridge, wherein the first and second radially facing contact surfaces are formed as part of the shell.
18. The filter cartridge of claim 17 , wherein the first and second radially facing contact surfaces are formed as part of an opening or cutout in a portion of the shell.
