REA/Vector Applicators Spray Techniques

Before operating, maintaining, or servicing any ITW Ransburg electrostatic coating system, read and
understand all of the technical and safety literature provided with ITW Ransburg products. If you do not
have the manuals and safety literature for your ITW Ransburg system, contact your ITW Ransburg
representative.

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.
