Abstract

Injektorvorrichtung zur Förderung von Beschichtungspulver in einer Pulverbeschichtungsanlage. Seine Luftkanäle (28, 26, 38) sind mit mindestens einer Pulversperre (28, 36) versehen, welche ein Filterelement aus mikroporösem Material enthalten, welches für Luft, jedoch nicht für Beschichtungspulver durchlässig ist und ein Eindringen von Beschichtungspulver aus dem Pulverkanal (4) und seinem Saugbereich (8) verhindert.

Figure 00000001
Injector device for conveying coating powder in a powder coating system. Its air channels (28, 26, 38) are provided with at least one powder barrier (28, 36) which contain a filter element made of microporous material which is permeable to air but not to coating powder and penetration of coating powder from the powder channel (4) and its suction area (8) prevented.
