between the spray gun and the work
piece.
Fig. 6: Setting the spray pattern
1. Set material flow via valves in control
cabinet or at material flow control (1).
Open the material flow control on
the spray gun when controlling
via the regulation cabinet.
2. Set atomizer air using valves in the con-
trol cabinet or on the atomizer air control
(R) (3).
Observe the following character-
istic curve.
3. Set horn air using valves in the control
cabinet or on the horn air control (F) (2).
ð When the horn air is blocked, the
spray pattern is round.
Characteristic curve
Fig. 7: Characteristic curve
1 Flat spray pattern
2 Round spray pattern
X axis Atomizer air pressure [bar (psi)]
Y axis Flow rate [Nl/min (CFM)]
The characteristic curves show the relation
between atomizer air pressure and air con-
sumption when using the air caps PL and
HM with a diameter of 1.0 mm as well as the
air cap PC with the diameter 1.6 mm.
To achieve the highest possible transfer rate,
the air pressure should be kept as low as
possible Ä 6.3 “Selecting air cap”, Ä 10.5
“Operating values”.
