Abstract (en)
[origin: WO0205925A1] The filter device contains a stack of filter rings (2), preferably consisting of plastic. Each filter ring (2) contains a number of cams (3) which are distributed evenly over the face, and diametrically opposed recesses. When the cams (3) and the recesses of adjacent filter rings (2) lie flush on top each other, a gap (7) is formed between them. The gap openings of the filter element (8), which consists of several filter rings (2) layered on top of each other, can be cleaned efficiently by means of a back-flow device comprising nozzle bodies (70). The characteristics of the filter can be altered by selecting a filter gap with different filter rings and different filter stack heights.
