Filtermodul und Verfahren zu dessen Herstellung

摘要

A filter module is formed of filter material. In the filter material openings (25) are formed wherein the boundary surfaces of the openings (25) constitute the flow-through surfaces (6) . The filter module is a roll (27) of wound filter material. The openings (25) of the wound layers of the filter material form channels (26) angled relative to the winding axis (9), wherein one group thereof opens at the outer peripheral surface (28) of the roll (27) and the other group opens at the inner peripheral surface (29) of the roll (27) and wherein the channels (26) on the other end, respectively, are closed and wherein the channels (26), angled relative to the winding axis (9), are separated from one another by filter material, and wherein the inner area of the roll (27) has a central channel (3) arranged around a winding axis (9).
