Abstract

Filaments, e.g. of synthetic fibre or metal wire, are wound between notches which are not diametrically opposed and the winding is continued until a double core network results, with a cylindrical void transverse to frame. Pref. the annular frame is flanged inside and out, so that windings are displaced from frame, thus permitting access under network, to increase area for filtration. The element has high area, and is simpler to fabricate than known wound filament elements. Several may be assembled apex to apex with interposed rings, fluid flows through elements in parallel, and cleaned fluid exits from central channel.
