5.2.1 MODE OF OPERATION
ORDER NUMBER DOC 2312956
GA 4000ACIC
Diagram:
SA = Shaping air AA = Atomizing air CA = Control air M = Product C = Circulation
Open:
The piston in the drive is charged with control air and moves toward the rear. This ensures that the air valve which releases the shaping and atomizing air is opened rst. The product valve is then opened with a mechanical delay. In this position, the pressurized coating product is applied to the work piece.
Close:
The piston is relieved, and the product valve closes due to the pressure spring which presses against the product valve tappet. The air valve is then closed, again with a spring force and mechanical delay.

Additional functions:
The shaping air throttle is used to regulate the shaping air volume, while the atomizing air is adjusted via an external pressure regulator. The two air streams do not ow separately until they are downstream of the air valve, so that the pressure of the shaping air corresponds roughly to that of the atomizing air and so that they inuence each other during adjustment. The product connections and the paint channels in the base plate are arranged so that several guns can run in circulation mode.

5.2.3 SPRAYING PROCEDURE
5.2.3.1 AIRCOAT FLAT SPRAYING PROCEDURE
For normal applications with the AirCoat at jet process, the spray product is atomized at a pressure of 3-12 MPa; 30-120 bar; 435-1740 psi. For normal applications, a soft, optimum spray jet is achieved with help of the atomizing air, which has a pressure of 0.05-0.25 MPa;
0.5-2.5 bar; 7.2-36 psi. This eliminates most overlapping problems in the peripheral zones. The shaping air allows the width of the spray jet to be increased or decreased.

5.2.3.2 AIRCOAT ROUND SPRAYING PROCEDURE
For normal applications with the AirCoat round jet process, the spray product is atomized at a pressure of 3-12 MPa; 30-120 bar; 435-1740 psi. For normal applications, the air at 0.05-0.25 MPa; 0.5-2.5 bar; 7.2-36 psi produces a soft spray jet. The spray jet can be adjusted by turning the nozzle nut.
The multi-channel swirl nozzle produces ne paint particles, while at the same time reducing their forwards speed and swirling them to produce a rotating motion. The result is a soft, extremely well atomized spraying cloud.
