FIELD: ventilation-and-draft systems, air mains, clearing of premises and streets by aspiration. SUBSTANCE: method involves generating air flow; dust intaking and conveying dust by air flow to dust discharge tract through continuous air channel, with longitudinal component of speed of air flow in air channel in the direction of movement being maintained exceeding or equal to zero and with average cross component of speed of air flow in one section of channel being maintained equal to zero by maintaining constant or reducing channel section area in the direction of flow and by maintaining equal channel tubes lengths. EFFECT: increased efficiency and enhanced reliability in operation. 2 dwg
