22GA 4000ACICB_03073OPERATING MANUALEDITION 06/ 2011 PART NO. DOC2312956Close:The piston is relieved, and the material valve closes due to the pressure spring which pressesagainst the material valve tappet. The air valve is then closed, again delayed by spring forceand mechanically.Additional functions:The shaping air throttle is used to regulate the shaping air volume, while the atomizing airis adjusted via an external pressure regulator. The two air streams do not flow separatelyuntil after the air valve, so that the pressure of the shaping air corresponds approximatelyto that of the atomizing air and so that they influence each other during adjustment.The material connections and the colour channels in the base plate are arranged so thatseveral guns can be used in circulation operation.4.5 SPRAYING PROCESSVariable spray jet widthAtomizing airIn the AirCoat process, high pressure of 3-15 MPa; 30-150 bar; 435-2176 psi is used toatomize the material. A soft, flat spray is achieved with help of the atomizing air, which has apressure of 0.05-0.25 MPa; 0.5-2.5 bar; 7.2-36 psi. The shaping air (C) provides the potentialto make the width of the spray jet larger and smaller.Advantages:• High painting capacity• Low fogging tendency• Good finish• High viscosity paints can easily be applied• Change in width the jet4.5.1 AIRCOAT ATOMIZING FLAT JET SPRAY PROCESSAir capShaping air
