You can set the spray pattern by using the
horn air and atomizer air.
You can vary the size of the spray
pattern by adjusting the distance of
the spray gun to the work piece and
the selected nozzle size.
Fig. 7: Setting the spray pattern
1. Close atomizer air control (1) and horn air
control (2) or atomizer air supply (R) and
horn air supply (F) completely.
If horn air and atomizer air are
blocked, atomization is done
exclusively through material pres-
sure (airless mode).
2. Adjust material quantity by means of the
nozzle size. Adjust material pressure air
through valves in the control cabinet.
Observe the following character-
istic curve.

3. Open horn air control (2) or horn air
supply (F), until the spray pattern no
longer has any offshoots (stripes).

4. The length of the spray pattern can be
adjusted by opening the atomizer air con-
trol (1) or atomizer air supply (R).

nozzle with a nozzle with a
smaller spray jet angle.
