1. An air cleaner arrangement comprising:
a filter element shaped as a polyhedron, the filter element and extending along and tapering with respect to an axis line between a first end surface and a second end surface, the first end surface and the second end surface orthogonal to the axis line, the first end surface being larger than the second end surface; a housing including a tubular shell adapted to receive the filter element, the tubular shell extending between a first shell edge and a second shell edge and having a cross-section corresponding in shape to the filter element shaped as a polyhedron, wherein the housing includes a first housing cover disposed at the first shell edge and a second housing cover disposed at the second shell edge, the second housing cover delineating an outlet port disposed therethrough, wherein the first end surface is formed by a first end cap disposed on the first element end of the filter element and the second end surface is formed by a second end cap disposed at the second element end, wherein the filter element comprises a filter media disposed about a center tube extending between a first element end corresponding to the first end surface and a second element end corresponding to the second end surface, the center tube generally concentric to the axis line, and wherein the plenum corresponds in part to a gap having a triangular profile with a first leg corresponding to a first sidewall of the tubular shell, a second leg corresponding to a portion of the second housing cover, and a hypotenuse corresponding to the first exterior surface of the filter element. |
