VERTICAL AIR INTAKE SYSTEM, AIR CLEANER AND FILTER ELEMENT Russian patent published in 2018 - IPC B01D46/24 F02M35/24 

FIELD: water and air purification technology.

SUBSTANCE: application describes air filter elements, air cleaners, vertical air intake systems, and methods for servicing and using. Air filter element includes a filter arrangement, an elbow, and a filter element seal member. 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. Elbow has a first end which extends 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. Air flow enclosure includes an air deflector 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. 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 and defines a seal member cross sectional area. Filter element has a ratio of the seal member cross sectional area to the filter arrangement cross sectional area of at least 0.5. Filter element can have a Z-filter media pack for a pleated media pack. Filter element can have the air deflector extending at an angle of at least 10 degrees relative to the first axial direction. Air deflector can include a projection surrounded by a recess. Access cover can include a recess that receives the air deflector projection, and a projection that is received within the air deflector recess. Air cleaner can be provided with a secondary filter element, which can have a recess for receiving the air deflector recess. Secondary filter element can include a projection that projects into the air deflector projection.

EFFECT: reducing the likelihood of air pollution.
