ABSTRACT:
In a powder atomizer for series coating of workpieces, additional air is led from a separate channel into the path of the powder-air mixture which exits from the powder channel of the atomizer, air which can be used during the coating to influence and change the mixture and, during pauses in the coating, as rinsing air for cleaning, for example, the powder path leading through an atomization bell.
