FIELD: engines, pumps.
SUBSTANCE: essence of the method consists in formation of vortex type air flow due to the input of impulses of the compressed air directed flow along a helical trajectory with simultaneous formation of a coaxial helical flow of sucking air. Vortex-type flow facilitates rapid activation and dust entrapment due to a flow rotation along a complex helical trajectory. During the process of activation and evacuation of dust the direction of the compressed air flow and the sucking flow can be reversed at every subsequent impulse or within one impulse. The suction air of the compressed air flow sucks dust along the central duct through a suction nozzle.
EFFECT: increase of quality and speed at cleaning rooms or electronic devices.
