Fluid Supply/Settings
During the sales process, your DUX representa-
tive will help you choose the proper tip size and
fluid pressure for your application. Due to the
efficient nature of the DUX gun, this flow rate
is likely to be 15-40% less than your existing
spray gun. However, if changes are made to
your production speed, coating type, or desired
finish quality, it may be necessary to use a
different fluid tip size or alter the other settings.
If you are using the DUX gun for the first time,
or have recently changed your operations, we
recommend the following steps.
First, identify the flow rate of your existing spray
gun to serve as a benchmark. To do this, turn
off the atomizing air at the air regulator and
trigger the gun into a beaker or measuring cup
for 15 seconds. Multiply the resulting volume
by 4 to calculate your flow rate in ounces or cc
per minute.
Next, because DUX guns are more efficient, we
recommend you choose a fluid tip that is one or
two sizes smaller than your existing gun. Also,
because the fluid control micrometer knob is
designed for very small adjustments only, we
recommend you begin with the fluid micrometer
set at the 4A position – which allows maximum
flow.

PLATINUM PRESSURE FEED
With the atomizing air turned off, trigger the
DUX gun over a beaker and use your fluid regu-
lator to adjust the fluid pressure. Regulate your
pressure so the fluid stream arcs approximately
8" from the tip of the gun (see Figure 4 ).
If you apply too much pressure at the regu-
lator your fluid stream will be much too fast.
Proper atomization may be difficult under these
conditions.
Test Spraying
Proper operation of the DUX Pressure Feed
requires the trigger handle to be pulled fully to
the rear of the spray gun while spraying. This
ensures uniform spray patterns and consistent
mil thickness.
Spray a test pattern and evaluate the finish
quality. Increase or decrease the flow by
increasing or decreasing fluid pressure until the
desired results are achieved. If necessary, small
incremental adjustments of the DUX fluid control
knob can be made. When the optimum results
are achieved, record the setting for simple future
setups.

Figure 5: Fluid Micrometer Markings
The markings on the fluid control knob (shown
in Figure 5) correspond to 0.1mm of needle
travel when the trigger is fully pulled (e.g., rotat-
ing the control knob from A to B increases the
needle travel by 0.1mm).
