Abstract
A tubular or cylindrical filter structure consists of a plurality of ring-shaped elements disposed in stacked relation by connecting rods and supporting a filtering media. The filtering media is disposed inside or outside the ring-shaped elements, depending on the direction of fluid flow therethrough. The ring-shaped elements protect the filtering media from tensile or compressive forces generated by the fluid flow, and at the same time present an open structure.
