Plug-in powder injector for organic powders 391 530

Plug-in powder injector for organic powders 391 530 with coded quick-release connections

The injector is used to convey normal organic powders between the powder hopper and the powder gun. The injector is

supplied with a PTFE insert sleeve as standard. The plug-in injector allows fast cleaning and easy handling because it can be

detached from the powder hopper without using any tools. All connections are plug-in and not interchangeable (when using in

manual equipment).

 Structure of the powder injector 

Principle of the injector

If air flows through the nozzle into the cavity, a vacuum is created in the cavity (see figure below). This vacuum causes powder to

be drawn up the suction tube and into the cavity. A powder/air mixture is created. The forward air velocity at the nozzle conveys

the powder/air mixture through to the powder hose to the gun.
