Zusammenfassung:A filter filters fluid flowing along an axial flow direction and includes a plurality of concentric cylindrical pleated filter elements having a common axis. A plurality of annular radial gaps between filter elements provide additional flow axially through the filter, providing equalized flow and reducing restriction. In further embodiments, a central filter element is concentrically surrounded by a cylindrical pleated outer filter element and provides additional flow axially therethrough.
