Cell for surface treating workpieces has roof wall with air outlet area whose outlet surface has partial area with local surface normal directed into interior of cell underneath remaining area of roof for better air flow and dust removal

摘要

the cell has a roof wall (110) with air outlet area (116) whose air outlet surface (140) through which air flows into the cell has at least a partial area where the local surface normal of the outlet surface is directed into the area of the cell interior arranged under the remaining area (118) of the roof wall. The air outlet area extends in a longitudinal direction and has a constant cross section across same. The air outlet surface is preferably convex seen from the inside of the cell.
