2.5.3. Blowing out the new powder supply
During a color change or when emptying the tank, the supply lines for new powder are blown by air streams to ensure
effective cleaning.
The air streams are sent successively to the suction pipe and to the tank.
2.5.4. Recycled powder supply to tank (production phase)
The recycled powder comes from the bottom of the cyclone or is then transported by the flip flop system of the
sleeve valves to the tank. Recycling of the powder starts when the high level sensor in the tank + tempo is lost. Airs
T21A and T22A are transport airs to evacuate the powder to the tank.
