METHOD FOR SUPPLYING AIR INTO A SPRAY BOOTH (EMBODIMENTS) AND A VENTILATION UNIT FOR IMPLEMENTING THE METHOD (EMBODIMENTS)

摘要

In the method (variant 1), a closed air stream is created inside the painting booth and air supply unit, after passing the painting zone it is divided into two streams, the first stream returning to the painting booth, while the second stream, containing flammable liquid vapors, is extracted to atmosphere. Simultaneously, some additional air is taken from atmosphere, mixed with return air and supplied to the paint booth painting zone. In the method (variant 2) a closed air stream is created inside the painting booth and air supply unit, and, after passing through the painting zone, is mixed with some additional fresh air and then divided into two streams, the first returning to the painting booth, while the second stream containing flammable liquid vapors, is extracted to atmosphere.
