RANSBURG 79580-42301 ASSEMBLY, AIR-ASSIST HANDGUN, 85 KV CASCADE

This is a combined air/airless method for electrostatically applying coatings to objects. The Vector AA90 Vector AA90 Vector AA90 Vector AA90 Vector AA90 system applies a high voltage DC charge to the applicator electrode, creating an electrostatic field between the electrode and the grounded target. The target is electrically grounded through its support which may be either stationary or moving.A regulated high pressure fluid system delivers coating material to the fluid nozzle and is atomized by passing through an orifice under pressure. The atomized spray particles become electrically charged under the influence of the electrostatic field surrounding the nozzle. The air supply to the applicator aids in shaping the coating material into a desired pattern. The charged particles are attracted to and deposited on the target object.The forces between the charged particles and the grounded target are sufficient to turn most normal overspray around and deposit it on the back surface of the target. Therefore, a high percentage of the coating is deposited on the target.One of the many features of the Vector AA90 applicator system is that the electrical energy,which is available from the resistive charging electrode, is limited to the optimum level of safety and efficiency. The system is incapable of releasing sufficient electrical or thermal energy during normal operating conditions to cause ignition of specific hazardous materials in their most easily ignited concentrations in air.The power supply provides voltage output to the applicator and contains controls for AC on/off,high voltage adjust, "one touch" triple setpoint, anddisplays kV and μA in real time

As the applicator electrode approaches ground,the power supply and applicator circuitry cause the high voltage to approach zero while the current approaches its maximum value.
