2.5.9. Blowing out powder feed pipes for sprayers.
The powder hoses of the sprayers are blown by two air supply sources.
1 By controlling the injection and dilution valves at maximum setting (once the powder tank has been emptied).
2 By alternately ordering KK20 valves L01... LXX. Air streams are sent to the sprayers and to the tank when the
QRPLXX sleeve valves for the air streams are opened.
2.5.10. Tank blowing
The tank has its own air supply via two air inlets on the rear panel. Valves QR45 and QR44 are closed during cleaning
air trains. The tank is also cleaned by the new and recycled powder supply pipes during the cleaning phases.
