SUBSTANCE: body of the device for cleaning ventilation air from dust is made in form of hemisphere and turns in equatorial part into slotted inlets which form in body space a circular channel extending along body and confined by external and internal hemispheres whose upper parts have deflecting cone and round hole, respectively. Internal hemisphere in equatorial part turns into duct collecting bin which consists of cylindrical and conical members accommodating coaxially located dust separator which consists of collector in form of reversed cone and internal fairing in form of spherical belt smoothly conjugated with each other to form hollow with slotted circular clear section. Located coaxially inside hollow is suction chamber of exhaust pipe brought outside from device. Clear sections of internal fairing and suction member are directed to opposite sides. Conical member of dust collecting bin has bevel cut closed with gate in its lower part. EFFECT: higher efficiency. 2 dwg
