The pneumatic nozzle cleaning unit cleans the application nozzles in the application process. Through an opening in the top panel, the application nozzle is inserted into the nozzle cleaning unit. The six jet nozzles, which are mounted on the top panel, remove excess material from the application nozzle with compressed air. To ensure the required air flow for effective cleaning, the system contains three compressed air vessels, which are continually supplied with compressed air. The built-in solenoid valves close during air-jet cleaning, the fast-acting ventilation valves switch immediately and the content of the compressed air vessels is immediately delivered to the jet nozzles. The excess material blown off is collected in the collection container in standard bin bags. The unit can be stationary or mobile, depending on the type of application tower.
