A side channel blower, preferably for burners for cleaning soot particle filters mounted in exhaust gas lines of vehicles by burning off, is shown, in which a chamber housing (6) with a chamber (5) is arranged on the air discharge side, wherein air flows into said chamber from the side channel blower (1) and said chamber permits adjustable return of air from said chamber into the annular channel (8) via a bypass (12, 13) and return of additional air, also into said annular channel (2), via an air transfer channel (9) that can be closed with a valve (16), and the air delivered can be fed from said chamber to the filters for cleaning by burning off via two air discharge openings (8a, 8b), which can be closed such that one discharge opening is open and the other discharge opening is closed.
