Savings of 25% to 50% in paint is possible when you replace conventional air spray with ITW Ransburg Electrostatic Applicators. You finish curved and recessed surfaces uniformly in fewer passes, because combined air and electrostatic forces literally follow the shape of the work surface. Bounce losses from work are reduced by the electrostatic attraction, when proper techniques are used.
The following describes basic electrostatic spray techniques. Depending on the type of work being sprayed, it may be necessary to change the technique slightly.

The size of the object being coated is the determining factor in adjusting the fan pattern; the larger the object, the larger the required fan pattern. Fan control of the ITW Ransburg REA/Vector applicators is accomplished by rotating the adjusting knob located at the rear of the applicator. Fan width can be set for approximately a 3-inch width (minimum) to approximately a 14-inch (maximum). Fan widths and overall pattern appearances are illustrated.

One of the most prevalent of "bad" spray painting habits is the one where the operator holds his arm steady and swings his wrist back and forth. This is a hard habit to break, it gives the illusion of adding speed to the coating operation, when in reality, it is slower and much more inefficient. Spray painting in this fashion results in light films on both sides, excessive film at center, and increased overspray with excessive "bounce­back."

The spray applicator should be maintained in a position at right angles to the object and should be moved in a path parallel to the object.

There may be instances where it is more practical to coat an object using vertical passes rather than horizontal. First, rotate the nozzle to shift the fan pattern, then holding the applicator at right angles to the object, move the applicator in a straight vertical path as illustrated.
