FIELD: machine building.
SUBSTANCE: dust/gas gate installed in materials treatment device contains casing, made with possibility of the machining tool installation in it, and connection with system for suction the generated dust/gas mixture, and device for dust/gas mixture in the casing. The device for dust/gas mixture contains assembly for directed supply of compression air to the machining zone from side of peripheral area of the machining zone, and element directing flow of dust/gas mixture, it has bottom surface located around the machining zone and being streamline for the dust/gas mixture flow.
EFFECT: increased efficiency of dust/gas mixture separation due to suction of fine dust cloud from powder, and assurance of the spraying process in production rooms without use of the suction chambers.
