FIELD: mechanical engineering.
SUBSTANCE: cyclone-type dust catcher has cyclone casing provided with suction member for sucking of air into casing, and discharge member for discharging of air therefrom, grid connected to discharge member and adapted for air filtering, dust reservoir connected to cyclone casing and adapted for collection of dust sucked therein through suction member, and flow guiding unit for preventing dust collected within dust reservoir from scattering, and for directing of contaminant matter contained in dust-laden air in descendant spiral orientation into dust reservoir.
EFFECT: increased efficiency by preventing collision of heavy contaminant matter with grid flange, accelerated collection of said matter in reservoir and reduced noise volume.
