Abstract: Panel filter elements having a pleat block and a seal member are described. The panel filter elements are arranged such that the seal members and pleat blocks can have curved and/or angled elements. The seal member of a filter element may be curved, angled, twisted, and/or has a varying cross-section. The inlet and outlet faces of the pleat block of the filter element may be curved and/or twisted instead of planar. In some arrangements, both the seal member of the filter element and the faces of the pleat blocks can be curved and/or twisted. The described filter elements may be may be flexible, such that the shape of the filter element and/or seal can conform to the shape of a filter housing, or rigid, such that the shape of the filter element remains substantially the same before and after installation into a filter housing.

Abstract: Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a first alignment portion disposed on the first housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element comprises filter media and a second alignment portion disposed on the first filter end. The second alignment portion is complementary to the first alignment portion. The installation of the filter element within the housing causes the first alignment surface and the second alignment surface to align to provide for engagement of a radial seal between the filter element and the housing.

Abstract: A system for providing air to an internal combustion engine comprises a crankcase ventilation unit that receives unrefined blowby gas from a crankcase, separates oil from the unrefined blowby gas, and discharges refined blowby gas. A conduit delivers the refined blowby gas to an air cleaner housing. The air cleaner housing comprises a first chamber that receives intake air through a first port, a second chamber that receives intake air from the first chamber and refined blowby gas from the conduit through a second port, and a third chamber that receives a mixture of intake air and refined blowby gas from the second chamber and discharges the mixture through a third port. A primary filter element filters the intake air as it passes from the first chamber to the second chamber. A secondary filter element filters the mixture as it passes from the second chamber to the third chamber.

Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.

Abstract: A filter element comprising a filter media and an outer surface. The filter media is formed in a closed loop, the closed loop defining a hollow interior extending along a longitudinal axis between a first end of the filter media and a second end of the filter media. The outer surface surrounds a perimeter of the filter element and is defined by a substantially circular first portion and at least one second portion. The first portion is substantially circular at a selected height of the filter media, and the at least one second portion is depressed relative to a circle defined by the substantially circular first portion at the selected height.
