<p>A filter apparatus and method utilize a filter element having a central winding frame and a length of fluted filter material wound about the frame with the flutes of the media oriented substantially longitudinally, to thereby provide for filtration of a flow of fluid passing axially through the filter element. The winding frame is a substantially open, truss-like structure, having a smooth outer periphery and an axially extending winding feature to facilitate pulling the media into intimate contact with the smooth outer periphery during fabrication of the filter element. A leading edge of the filter media is anchored to a leading edge of the frame by a length of tape.</p> |
