The functional principle
Compressed air from the feed air connection is pushed through the injector nozzle (also known as the Venturi nozzle) into the collector nozzle. The small diameter of the nozzle ensures a high air velocity
On its way through the injector the feed air passes across the powder suction tube where it sucks in powder due to the vacuum. The air and the powder now continue to flow at a high velocity through the collector nozzle into the powder hose and finally to the spray gun .
The feed air is responsible for the powder quantity. In order to influence the powder velocity, dosage air is also required.
The air flow rate which you set on the controller consists partly of feed air and partly of dosage air. The ratio of dosage air to feed air has a great influence on the amount of powder delivered:
Wear
The abrasive effect of the powder/air mixture wears the collector nozzle over time. The powder speed decreases with increasing wear of the collector nozzle. The result is a reduction of the Venturi effect and consequently of the powder output.
In order to maintain the desired powder output the experienced powder coater increases the feed air at this point. Normally, this measure works until the collector nozzle is completely worn and must be replaced.
Typically, the life span of a collector nozzle lies between two weeks and one year (depending on the powder characteristics, the feed air quantity used etc.)
