A dust collector arrangement in which a filter chamber separated into two compartments by a layer of particulate filter medium receives partly purified gas from a centrifugal separator, and the filter layer is regenerated periodically by blowing collected dust particles back into the separator, is provided with an auxiliary circuit arranged between the separator and the source of raw gas communicating with the separator. The auxiliary circuit includes a cyclone separator of smaller effective diameter than the centrifugal separator. |
