After more than 5 years of research and
development, DUX has reinvented th e spr a y gun
from the inside out. By incorporating our
patented airflow technology, originally used in
Formula Three race car engines, we’ve
developed the most innovative breakthrough in
spray gun technology in nearly 80 years.
For the first time, finishers can spray nearly any
type of fluid, onto nearly any surface with a
single gun – while reducing coatings waste and
improving finish quality.
TECHNOLOGY THAT’S EASY TO USE AND
EASY ON US.
Patent Information
The design and technology forming the basis of
this product is the confidential information of DUX
Technologies Inc.,aWashington corporation.
The relevant US Patent Numbers are: US
6,793,157; US 6,425,533, and U.S. 7,004,404.
DUX Technologies Inc. may have additional
patents, patent applications, trademarks,
copyrights, or other intellectual property rights
covering subject matter in this document.
Except as expressly provided in any written
license agreement from DUX Technologies
Inc., this document does not grant you any
license to or rights in any such patents,
trademarks, copyrights, or other
intellectual property.
The DUX Automatic spray gun uses a patented
technology to reduce overspray and booth “fog”.
Less paint in the air means more paint on the
target and a corresponding decrease in booth
filter replacement and hazardous waste disposal
potentially cutting the operating cost of a
fees,
paint line by 50%. Since the DUX Automatic
achieves atomization with a lower volume of air,
you may also see a reduction in compressor
energy consumption.
Coatings and solvents may be extremely flammable or combustible. Always use the equipment
in a properly ventilated area. Smoking must never be permitted in the spraying area. Make sure
that all ignition sources are well out of range and always keep fire extinguishing equipment in
the spraying area.
Some solvents may cause eye injury during operation and/or while cleaning the equipment.
Always wear eye protection when working with the equipment.
Always read the MSDS supplied by the material manufacturer.
Some coatings and solvents may be harmful if there is contact
Always make sure to read the MSDS supplied by the material manufacturer. Always use the
equipment in a properly ventilated area. If there is a chance of inhalation or contact with skin,
use protective gear such as a respirator and/or proper clothing as suggested by the MSDS.

Installation
Mounting
When using the supplied mounting bolt, install the
spray gun onto a mounting rod 1/2” and tighten
using the hex screw. The mounting bolt can be
attached to either side of the spray gun by simply
unscrewing the bolt and reversing position.
Fittings
The DUX Automatic spray gun uses push-lock
style fittings as standard equipment. To attach the
hoses, insert one end of the hose into the fitting
until it’s locked it into place. To release the lock,
push the plastic locking ring toward the fitting
while removing the hose (See Figure 2).

AUTOMATIC
Fluid Control Knob
The fluid control knob is located at the rear of the
spray gun (See Figure 3). To increase the fluid
flow, turn the fluid control knob
counter-clockwise. Conversely, turn the fluid
control knob clockwise to reduce the fluid flow.
Once the desired settings have been achieved,
turn the fluid control locking ring clockwise to
lock the fluid control knob into place (See Figure
3).
!
NOTE: If the fluid control knob stops offering
resistance, maximum needle travel has been
reached. If the flow rate is insufficient, increase
the fluid tip and needle size.

Autom
for automatic fan adjustment have an additional
push-lock fitting for fan control. Air is externally
supplied to the air horns of the air cap to control the
size and shape of the spray pattern. The more air
pressure applied, the larger the fan pattern. When
the optimal results are achieved, record the input
pressure settings for simple future setups.
Manual Fan Adjustment:
manual fan adjustment have a fan control valve
with a locking ring (See Figure 4). Pattern shaping
air is obtained from the main air chamber of the
spray gun. With the fan control valve in the fully
closed position (i.e. no threads showing), a
minimum spray pattern size is achieved. Pattern
size increases as the adjustment knob is rotated
counter-clockwise, allowing more air to be directed
to the air horns. When the optimal results are
achieved, turn the locking ring clockwise to lock
valve in place.

Fan Control Adjustment
The fan control adjustment is located on the side
of the spray gun near the air cap. This
adjustment controls the amount of air delivered
to the horns of the air cap for spray pattern
shaping (See Figure 4).
!
NOTE: Applying excessive air to the air cap will
result in a split pattern.

IMPORTANT: Some coating leakage out of
the fluid tip may indicate an adjustment of the
packing is needed. This is not an indication of
the spray gun failing.
Always ensure the spray gun is depressurized
before making adjustments.
Fluid Packing Adjustm
The fluid packing in all DUX spray guns is set
to a pre-determined specification during
assembly. Therefore, depending on the type of
material being sprayed, it is possible that the
packing will need adjustment upon start-up or
after some amount of spraying.
Fluid leakage at the front of the spray gun is
an indication that the fluid needle is not
seating properly in the fluid tip. This may be
caused by dried material in the tip, or if the
fluid packing is too tight. If the packing is set
too tightly for a particular material, the needle
will not to fully seat in the fluid tip and will
require adjustment.
The DUX Automatic features a leak indicator
in the form of a pin hole located above the
mounting bolt (See Figure 9). Fluid leakage at
this pin hole indicates that the fluid packing is
too loose and will need tightening.
