PCT No. PCT/SE89/00070 Sec. 371 Date Sep. 27, 1990 Sec. 102(e) Date Sep. 27, 1990 PCT Filed Feb. 17, 1989 PCT Pub. No. WO89/08938 PCT Pub. Date Sep. 21, 1989.An arrangement for transporting air with the aid of corona-wind including tubes to extract detrimental side effects from corona discharge. A first tube is arranged with an open end located downstream of and axially in line with the corona electrode, as to face towards the electrode and such that the air flowing past in the vicinity of the corona electrode will flow into the open end of the first tube. A second tube having an open end is positioned upstream of and axially in line with the corona electrode, this second tube being directed downstream. The first tube and the second tube are connected together so that the air flowing in through the open end of the first tube will be conducted to the second tube and flow out through the open end of the second tube in the immediate vicinity of the corona electrode.
