Effects of air separators on the improvement of stalling characteristics of axial flow compressors were investigated on a lowspeed single-stage fan. The best arrangement of the air separator has proved to be able to eliminate completely the stall zone of the original solid-wall characteristics with almost no loss in the stage efficiency. The effective relative axial location of the device against the rotor blade tip suggested that the improvement has been achieved by the separator continuously removing deteriorated flow around the blade tips.
