Abstract (en)
[origin: EP0817223A1] The mesh may be triangular formed by alternately undulating wires tangential to a straight wire in the median plane. At least one mesh has the two wires undulating alternately under and over the straight wire in opposite senses. An alternative has the wires overlapping, passing above and below two straight wires and shifting relative to preceding wire. The diameter of the undulating wires is less than that of the straight wires. The opening may have three layers of rep or mesh which get progressively finer as the gas passes through. The first layer has undulating and straight wire of diameter above 0.5 mm with a nominal opening greater than 400 mu m while the last layer has a nominal opening less than 200 mu m.
