CROSS-FLOW FAN WITH A CLOSED SUCTION ELEMENT, AND SMOOTH FLOWING SUCTION SEPARATION DEVICE

摘要

The invention relates to a cross-flow fan that may also be operated in suction mode, mainly in air-ducts with a large width, to provide a smooth flow of regulatable air. The invention also relates to a smooth flow suction separation device that is suitable for the regulated suction to a large width of an air amount containing a solid fraction, and for the separation of the solid fraction on the inlet side, and in certain forms of its construction with the flow of air being made to circulate. The smooth flowing suction separation device, is equipped with a curved centrifugal separation device (8), a fraction outlet (9, 10, 11). The characteristic feature of the invention is that it has a cross-flow rotor (2), a house (1) constructed as a pneumatic duct (13) and a closed suction element (3) attached to the internal edge of the centrifugal separation device (12).
