Assist air can be adjusted either locally (at the
applicator) or remotely (air regulator or analog
function).
Locally Locally Locally Locally Locally
Assist air is adjusted by turning the control knob
[57] on right side of applicator (from rear of
applicator). A counter-clockwise adjustment will
increase assist air and reduce “tails” and generally
increase pattern.

Assist air is controlled remotely by the use of an
air regulator or a programmable controlled analog
function.

The distance between the applicator and the target
influences the appearance of the final finish coating
of the object. If the applicator is held too close
(under 4-inches), runs and sags with excessive
“bounce-back” may occur. If the applicator is held
too far from the object, the electrostatic attraction
is decreased. Normally, the best spacing between
applicator and target is in the 6 to 12-inch range.
Overlap Overlap Overlap Overlap Overlap
For the best “hiding” and uniformity of film
thickness, the stroke overlap should be
approximately 50%. There should be some
Overlap at edges of the part to increase edge
coverage. overlap requirements may vary widely
with different paint formulations and different paint
formulations and different compositions of objects
being coated. Individual spray coating operational
experience should provide the guide lines for
efficiency in this instance.
T T T T Triggering riggering riggering riggering riggering
Applicator triggering (ON-OFF) depends largely
on the desired results (the amount of wrap-around
required, edge coating, etc.). If the front and back
of the object are being coated, proper applicator
technique can edge coat in some instances without
making a specific pass for that purpose.
Triggering the applicator before the target is
directly in front of the applicator may cause heavy
edge build-up on the leading edge of the target
due to the electrostatic attraction.

A selection of the proper paint mixture is essential
to electrostatic operation. Paint test equipment
may be obtained through your ITW Ransburg
representative. Consult the following ITW

testing procedures, consult your ITW Ransburg
representative and/or paint supplier.

precision is paramount to prior functions. ITW
Ransburg makes every effort to assure that all
production of this part will meet the critical design
standards necessary for all applications.
