Compressed air powered suction generator

摘要

In a compressed air powered suction generator comprising bin 1 with suction inlet 2 and ejector 11 supplied with compressed air via hose 5 and valve 6, the exhaust air flow from the ejector together with entrained air entering the bin via the suction inlet is directed through the passageway between cone 9 and casing 12 to an annular slot between plate 8 and dome 7 and issues therefrom downwardly along the surface of the dome because of the Coanda effect. A filter 3 may be located in the bin. Improvements in noise reduction and safety are said to result.
