Mobile jet machine for surface-treating substrates comprises a suction device arranged between an accelerating device and the curve of a rebound channel

摘要

Mobile jet machine (1) comprises an accelerating device (4), a suction device (20), and a rebound channel (5) returning spraying agent rebounding from the substrate back into the jet machine. The suction device is arranged before the curve of a curved rebound channel, i.e. between the accelerating device and the curve of the rebound channel. Preferred Features: The suction device is arranged in the region between the accelerating device and the substrate to be treated or in the region between the substrate and the end of the rebound channel. A separator (21) having a rotating magnetic wheel (26) is provided at the end of the rebound channel.
