Air filter elements, air cleaners, vertical air intake systems, and methods for servicing and using are provided. An air filter element includes a filter arrangement, an elbow, and a filter element seal member. The filter arrangement includes a filter media pack having a dirty air inlet and a clean air outlet, wherein air flowing through the clean air outlet flows in a first axial direction and the clean air outlet defines a filter arrangement cross sectional area. The elbow has a first end constructed to extend from the filter arrangement clean air outlet, a second end wherein air flowing through the second end flows in a second axial direction, and an air flow enclosure extending from the elbow first end to the elbow second end. The air flow enclosure includes an air deflector constructed to direct air from the first axial direction to the second axial direction, wherein the second axial direction is different from the first axial direction, and an interior volume between the elbow first end and the elbow second end. The filter element seal member is located on the elbow second end, wherein the filter element seal member is constructed to seal to a clean air intake, the filter element seal member located on the elbow second end defining a seal member cross sectional area. The filter element can be characterized as having a ratio of the seal member cross sectional area to the filter arrangement cross sectional area of at least 0.5. The filter element can have a z-filter media pack for a pleated media pack. The filter element can have the air deflector extending at an angle of at least 10 degrees relative to the first axial direction. The air deflector can include a projection surrounded by a recess, the access cover can include a recess that receives the air deflector projection, and the access cover can include a projection that is received within the air deflector recess. The air cleaner can be provided with a secondary filter element and the secondary filter element can include a recess for receiving the air deflector recess. The secondary filter element can include a projection that projects into the air deflector projection. |
