摘要

The present invention relates to a dust separator, comprising a cyclone (1), which supports at least one fan (5), by means of which dust- mixed air is sucked into the cyclone (1) through at least one suction opening (7) and is brought to pass one or more shell-shaped filters (2) before the cleaned air is blown out through at least one exhaust opening (5.4), the cyclone (1) being divided into an upper room (1.5) and a lower room (1.6) by a partition wall (1.4), in which the respective filter (2) is arranged, projecting down into the lower room, at least one clean blowing device being arranged to blow compressed air from behind through the respective filter (2) when the same has become clogged by dust. The filters (2) are covered by at least one lid (3), which has at least one opening (3.1) for the respective filter (2), in which at least one valve device (3.2, 3.3, 3.4) for cleaned air is arranged. Said at least one lid (3) supports at least one clean blowing nozzle (6), which mouths on the underside of the lid (3), and the clean blowing nozzle (6) stands in communication with at least one source of compressed air via at least one pilot valve (6.2).
