2.5.7. Draining the powder tank
The tank is emptied when the colour is changed or when production is completed.
2.5.8. Powder supply for sprayers (powder hose)
The powder supply to the projectors is managed by the venturi pump. The injection air acts on the powder flow
and the dilution air on the transport air to bring the air/powder mixture to the projector in a homogeneous manner.
