Abstract:
An aspirator for oil mists for machine tools and other machining devices, comprising: a substantially cylindrical external enclosure having a longitudinal axis; at least one impeller; an electric motor for driving said at least one impeller, said electric motor and at least one impeller being accommodated in said enclosure; a filtering module for filtering air aspirated by said impeller and passed through the filtering module; a supporting frame for supporting said enclosure so as to oscillate from a working position in which the longitudinal axis thereof is vertical with respect to a resting plane of said supporting frame, to a working position in which said axis is horizontal with respect to said supporting plane, and further comprising a drainage tube for conveying outside said enclosure oil recovered by filtration of oil-saturated air passing through said filtering module, said drainage tube extending from a location point of an external surface of said enclosure, along an axis thereof, said tube axis being angled with respect to a plane being tangent to the external surface of said enclosure, in said location point.
