Abstract

A filter module is formed of wound filter material having openings wherein the boundary surfaces of the openings constitute flow-through surfaces. The openings of the wound layers of the filter material form channels angled relative to the winding axis, wherein one group thereof opens at the outer peripheral surface of the roll and the other group opens at the inner peripheral surface of the roll and wherein the channels on the other end, respectively, are closed and wherein the channels, angled relative to the winding axis, are separated from one another by filter material, and wherein the inner area of the roll has a central channel arranged around a winding axis.
