Abstract

A filter housing (10) having a raw-side inlet (12) and a clean-side outlet (14) for media to be filtered and a forward-mounted part designed as a cyclone pre-separator (20) including at least one fastening region (32) of a first part (30) made substantially of plastic is fastened to the raw side, and a second part (40) braced between the first part (30) and the filter housing (10). The fastening region (32) of the first part (30) is screwed to the filter housing (10) using metal fastening elements (50, 54, 56, 60), and—at the upper side facing away from the filter housing (10) it has at least one pressing contour (70) for compensating for at least one dimension tolerance of the elements fastened together. The contour is substantially plastic material, which can be deformed by means of applying a force generated by the screwing together of the metal fastening elements (50, 52, 56, 60), in particular which can be melted.
