ABSTRACT:
The present invention relates to a device for separating particles from flowing medium, whereby separation of coarse particles occurs in a cyclone member (4) and separation of fine particles in a filter device (10) inside the cyclone member. For providing this separation of coarse particles in a cyclone member and additionally, fine separation in a cleanable filter device, there is, inside the cyclone member (4), provided a filter cleaning device (15) which engages filter material (16) included in the filter device (10) for cleaning said filler material from particles adhering thereto when the filter device (10) is rotated relative to the filter cleaning device (15), the filter cleaning device (15) relative to the filter device (10) or the filter device (10) and the filter cleaning device (15) relative to each other.
