Abstract:
1. A filter assembly comprising a filter element extending laterally along a lateral plane, an element plate extending laterally outwardly from said filter element to a perimeter, first and second housing shells axially spaced along an axial direction, said axial direction being transverse to said lateral plane, said filter element being axially between said first and second housing shells, said element plate having a first side axially facing said first housing shell and defining a first plenum therebetween, said element late having a second side axially facing said second housing shell and defining a second plenum therebetween, a first set of one or more windows formed axially through said element plate and passing flow axially between said first and second plenums, a second set of one or more windows formed axially through said element plate and passing flow axially between said first and second plenums, wherein said filter assembly has a flow path therethrough through said first set of one or more windows then through said filter element then through said second set of one or more windows, such that said filter element lies along said flow path between said first and second sets of one or more windows, wherein said flow path has a first segment extending axially through said first set of one or more windows in a first axial direction, a second segment extending laterally along said first plenum and then at least partially axially through said filter element and then laterally along said second plenum, and a third segment extending axially through said second set of one or more windows, wherein flow along said first segment of said flow path flows in a first axial direction through said first set of one or more windows, and flow along said third segment of said flow path flows through said second set of one or more windows in the same said first axial direction.
