PLATINUM PRESSURE FEED
The DUX Platinum Pressure Feed
INSPIRED BY FORMULA RACE CAR
ENGINES.
Once again, DUX has reinvented the spray gun
from the inside out! Built upon the success of the
original DUX Pressure Feed spray gun, the new
“Platinum” series gun is the next step for-ward in
spray gun evolution. We’ve maintained our pat-
ented Advanced Laminar Airow technology, but
we’ve added more user friendly features and a new
coating with embedded PTFE for easier cleaning
and longer parts life.
As always, nishers can spray nearly any type of
uid, onto nearly any surface with a single gun,
while reducing coatings waste and improving nish
quality.
TECHNOLOGY THAT’S EASY TO USE
AND EASY ON US.
Most pressure feed spray guns incorporate a front-
heavy body design with uid hose connections
near the tip of the gun. Over the course of a long
work day, the extra weight causes arm fatigue and
uneven spray patterns that impact nish quality.
The DUX Platinum Pressure Feed gun, however,
is designed with much shorter air passages, an
upright handle, and uid and air connections lo-
cated at the base of the gun. This creates a lighter,
more compact and balanced gun that’s easier to
maneuver in small spaces.
Lower operating pressures also result in mas-
sive reductions of unhealthy paint booth fog and
overspray. This drastically improves the work
environment for everyone involved.

Connect a clean air supply
Connect a clean, dry air supply to the Platinum
Pressure Feed via the 1/4” NPS air inlet tting.
Note that many compressed air systems may
be contaminated with particulate, compressor
oil and/or water. These materials can foul the
inside of the spray gun, leading to gun malfunc-
tion or defects in your nal nish. If you have
any question regarding the quality of your air
supply, please contact DUX for recommenda-
tions on proper air lter/dryer equipment.
Set Initial Air Pressure
As a starting point, adjust the air regulator to
achieve approximately 5 psi at the base of the
spray gun when the gun is triggered. Keep in
mind that hoses cause a drop in air pressure, so
it may be necessary to set the pressure at your
regulator well above 5 psi to maintain 5 psi at
the base of the gun. To ensure you begin with
the proper pressure, it is a good idea to install a
separate gauge (or a small regulator) at the base
of the gun.
Air Pressure:
Wall / Pressure Pot Regulator
5 Psi
Here
Figure 3: Pressure Gauge Installation
Due to DUX’s the patented Advanced Laminar
Air-ow design, a setting of 5 psi at the base of
the gun will result in approximately 5 psi at the
air cap—which is sucient to atomize many
coatings at a moderate uid ow rate.
Later, when test spraying the gun, you will adjust
the air pressure up or down depending upon
atomization quality with your particular coating.
Be sure to make a note of the triggered pressure
reading at your regulator at that time. This will
allow you to easily return to the proper gun set-
tings in the future. Also, remember to adjust your
settings if you change hoses, since pressure
drop will vary depending upon the length and
diameter on the hose used.
Connectaltereduidsupply
A clean uid supply is also required for reliable
gun performance and a high quality nish. For-
eign objects (typically dried chunks of coating)
will cause surface defects and may foul the uid
tip and needle—leading to leaks.
We highly recommend the installation of a high
quality uid lter as close to the gun as possible.
The size and type of lter will depend upon your
coating and application. If you have any ques-
tions regarding the quality of your uid supply,
please contact DUX for recommendations on
proper uid ltration equipment.
Connect your properly ltered uid supply to the
DUX Platinum Pressure Feed via the 3/8” NPS
uid inlet tting at the base of the gun as shown
in Figure 2.
Set Initial Fluid Pressure
Three elements control the uid ow rate
through the DUX gun:
1) Fluid Inlet Pressure
2) Fluid Tip Size
3) Fluid Micrometer Settings
Note Unlike traditional HVLP and Conven-
tional Air Spray guns, very little air pressure is
lost inside the DUX gun. It is not necessary
to begin with high pressure (30+ psi) at the
gun inlet.

O
peration Guide
Fluid Supply/Settings
During the sales process, your DUX representa-
tive will help you choose the proper tip size and
uid pressure for your application. Due to the
ecient nature of the DUX gun, this ow 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
nish quality, it may be necessary to use a
dierent uid tip size or alter the other settings.
If you are using the DUX gun for the rst time,
or have recently changed your operations, we
recommend the following steps.
First, identify the ow rate of your existing spray
gun to serve as a benchmark. To do this, turn
o 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 ow rate in ounces or cc
per minute.
Next, because DUX guns are more ecient, we
recommend you choose a uid tip that is one or
two sizes smaller than your existing gun. Also,
because the uid control micrometer knob is
designed for very small adjustments only, we
recommend you begin with the uid micrometer
set at the 4A position – which allows maximum
ow.
Figure 4: Proper Fluid Stream
With the atomizing air turned o, trigger the
DUX gun over a beaker and use your uid regu-
lator to adjust the uid pressure. Regulate your
pressure so the uid stream arcs approximately
8” from the tip of the gun (see Figure 4 ).
If you apply too much pressure at the regu-
lator your uid stream will be much too fast.
Proper atomization may be dicult 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 nish
quality. Increase or decrease the ow by
increasing or decreasing uid pressure until the
desired results are achieved. If necessary, small
incremental adjustments of the DUX uid control
knob can be made. When the optimum results
are achieved, record the setting for simple future
setups.
Adjusting Fluid Control Knob
The markings on the uid 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).
Knob Leteters
Yoke Numbers
Figure 5: Fluid Micrometer Markings

For customer service call 888.389.2732 Page 8
PLATINUM PRESSURE FEED
Operation Guide
The markings on the trigger yoke indicate
1.0mm of needle travel (e.g., a micrometer set-
ting of 1A equals 1.0mm of needle travel and a
setting of 2A indicates 2.0mm of needle travel).
NOTE: Maximum needle travel is 4mm,
making settings beyond 4A unnecessary.
Needle travel/uid ow is not increased
beyond this point.
Changing Fluid Tips
Unlike other spray guns that require a matched,
or “lapped”, set of needles and uid tips, the
DUX Pressure Feed uses a standard universal
uid needle. The needle does not have to be
changed when dierent uid tips are installed,
and a new needle does not have to be purchased
with each new uid tip.
Of course dierent coatings or coating applica-
tions may require dierent sized uid tips. DUX
oers a range of tips from 0.4mm to 2.2mm
in .2mm increments. Due to the precision
machining of DUX parts, no gasket or o-ring is re-
quired between the tip and the uid barrel.
To change tips, follow these instructions:
1. Ensure spray gun is depressurized.
2. Remove the air cap retaining ring and
air cap.
3. Pull the trigger to the rear.
4. Using the DUX 10mm uid tip driver,
remove the uid tip and inspect
threads for wear or contaminations
5. Install a new uid tip and tighten using
the DUX 10mm uid tip driver.
6. Replace the air cap and air cap
retaining ring
IMPORTANT: To maintain the precise t and
seal between the uid tip and the stainless
steel uid barrel, paint must not be allowed to
dry on the threads. The threads of both the
uid barrel and tip must be thoroughly cleaned
after each use.
Fan Control Knob
The fan control knob is located on the top
front of the spray gun and is shown in Figure 6
be-low. This knob controls the amount of air
delivered to the horns of the air cap to shape
the spray pattern. The largest fan pattern is
achieved with the fan control knob pointing
toward the spray target—or the 12 o’clock
position. Spray pattern size decreases as the
knob is rotated in either direction from the fully
forward position. Minimum spray pattern size
is achieved with the fan control knob pointed
toward the rear of the spray gun—or in the 6
o’clock position.

Cleaning & Maintenance
Proper care and maintenance procedures
must be used with the DUX gun to maintain
the product warranty. To assist in the cleaning
process, DUX provides proper cleaning
supplies with each gun including, brushes,
and lubricant. Optional Cleaning Caps are also
available for purchase.
CAUTION:
• Do not submerge the spray gun in
solvents or cleaning solutions—even with the
cleaning caps installed
• Do not clean air cap holes with metal
tools as it could eect the spray pattern
• The DUX Pressure Feed may be
cleaned in a spray gun washer with the clean-
ing cap(s) installed
Optional Cleaning Caps
DUX sells optional upper and lower Cleaning
Cap to protect the gun’s air chamber during
cleaning. If proper use of these caps is not fol-
lowed, uid can enter the air chamber and may
ultimately reach the air valve piston assembly . A
build up of uid in the air passage can negatively
impact laminar air-ow and the gun’s eciency.
Fluid build up in the air valve assembly may also
cause the valve to stick. Without the cleaning
caps in place, there are several ways in which
uid can enter the air passage:
*The uid tip is removed without depressurizing the
spray gun, allowing coating to run directly into air
chamber.
*Holding the gun “face up” while cleaning, allowing
paint and contaminated solvent to run down into air
chamber.
*Submerging the gun in a bucket or tank of dirty
solvent, allowing the contaminants to inltrate the air
valve area..
For this reason, always be sure to install the
cleaning caps (shown in Figure 8 below)
BEFORE removing the uid tip. To install, simply
thread the upper cleaning cap onto the gun just
as you would an air cap. Hand tighten until
snug. Install the Lower Cleaning Cap on the air
inlet of the gun.
The air chamber is now eectively sealed from
both ends. Use the nut driver to remove the
uid tip and begin cleaning.

Lubrication Guide
DUX spray guns are shipped pre-lubricated and a tube of silicone-free PTFE grease lubricant
is enclosed in each box. To ensure the quality and longevity of the DUX spray gun it must be
lubricated before every use and after every cleaning. Follow the diagram in Figure 9 to ensure
proper lubrication

Periodic Maintenance
Cleaning the Air Valve
If proper cleaning procedures and equipment
are not used, you may experience a sticky or
slow moving air valve piston. As a short term
solution, it is acceptable to introduce a small
amount of CLEAN solvent directly into the air
chamber. Simply remove the air hose, invert the
gun, and introduce solvent directly into the air
inlet. Squeeze the trigger several times while
applying the solvent. This should temporarily
free the air valve for continued spraying.
If sticking continues, a more thorough cleaning
of the air valve will be required. This procedure
involves the removal and cleaning of the trigger
air valve assembly as follows:
• Ensure the spray gun is depressurized.
• Unscrew the trigger spindle screws and
remove the chrome trigger handle. (See
Figure 11)
• Using standard retaining ring pliers,
remove the trigger air valve retaining
ring.
• Remove the air valve piston assembly
shown in Figure 12 from the gun body.
• Clean the valve by rinsing in clean water
or clean solvent.
• Clean the inside of the valve bore on the
gun body using clean solvent and a
brush.
• Dry both the piston and the gun body
thoroughly.
• Insert the trigger air valve assembly into
the body and use the retaining ring to
secure it.
• Replace the trigger handle, nylon washers,
and trigger spindle screws.
• Lubricate according to the Dux Pres
sure Feed lubrication instructions on

PLATINUM PRESSURE FEED
Platinum 3K Series: Fluid Packing
The Platinum Pressure Feed spray gun incorpo-
rates a new self-adjusting packing. No manual
packing adjustment is required. The packing
device uses an internal spring to apply consistent
pressure to the PTFE uid seal—keeping uid
from leaking past the seal while allowing for easy
triggering.
Because packing components in all spray guns
will wear over time, however, it may be necessary
to replace them periodically. Symptoms of a
worn packing include uid leaks from either the
front or back of the gun.
If uid is leaking from the front of the gun (via
the uid tip) be sure to rst inspect the tip to
ensure dried material or other foreign matter is
not lodged in the tip. Any such obstruction will
keep the uid needle from fully seating in the tip,
leading to the leak. If uid is leaking from the
back of the gun, it is generally an indication that
the packing is worn. In this case, the packing
should be replaced.
There are two methods for replacing the packing
in the Platinum Pressure Feed gun:
1) Replacing the entire packing
cartridge
2) Replacing the wearable packing
components.
Replacing the packing cartridge is faster and
simpler, but requires the purchase of a complete
re-placement cartridge. Replacing the individual
components is less expensive and is quite easy.
Below is a description of both methods.
Option #1: Replacing the Packing Car-
tridge
The replacement packing cartridge includes new
Stainless Steel housing components as well
as the new wearable parts (spring, PTFE uid
seal, and o-rings—all fully assembled into a
single unit. The part number for the cartridge is
#310127
To replace the cartridge follow these steps:
1. Ensure the gun is depressurized.
2. Unscrew the uid control knob and
completely remove the needle
assembly.

4. Remove the packing cartridge
from the spray gun body by
rotating it counter-clockwise
using the Dux Multi-Tool Wrench
5. Install the new packing cartridge,
(including the o-ring on the
cartridge) back into rear of the gun,
and tighten to 2 ft. lbs. of torque.
6. Inspect yoke and c-clip for wear or
contamination and reinstall; replace
if needed. Be sure to install the yoke
with the micrometer markings facing
up.
7. Lubricate the uid needle as
indicated in Figure 10 and reinstall
uid needle assembly.

PLATINUM PRESSURE FEED
Option #2: Replacing Pack-
ing Components
Because the stainless steel packing housing
components are very durable, it may be more
cost eective to change only those packing
components that will wear over time. Using
this method, you will need DUX Part Number
#310130—the Wearable Packing Component
Kit.
To replace the components, rst follow steps
1-4 on the previous page to remove the pack-
ing cartridge. Then follow these steps:
Removing the packing components
1. Unthread the knurled Spring Cap by hand
until it releases from the cartridge housing.
2. Remove the Sleeve B Spring and Sleeve B
to expose the brass Fluid Seal Nut on the inside
of the packing cartridge housing.
3. Use a at bladed screwdriver or the
packing replacement tool to remove the nut by
turning counterclockwise (be careful as there is
a spring beneath the cap).
4. Turn the housing upside down to re-
move the nut and spring. Note that the spring
is sized for an interference t inside the base
of the nut, so they should come out as a single
unit.
5. Use the pointed end of the packing
replacement tool to push/pick the PTFE uid
seal and black o-ring out of the base of the
housing. It may be easiest to access these
pieces from the outside of the housing. Clean
the inside of housing thoroughly before insert-
ing new packing components.
Important: Be careful when removing the
Spring Cap & Packing Nut-Content are under
spring pressure and may pop loose
Figure 14: Packing on tool
1. Using the packing replacement tool,
line up the replacement components as shown
in Figure14. Be sure the slot on the brass nut
lines up with the cross piece on the tool so the
tool can be used as a screwdriver to turn the
nut.
2. Push the components into the canal
on the inside of the housing as shown in Figure
15. When the brass nut seats at the base of the
housing, begin turning clockwise to thread the
nut.
3. Thread the nut as far as it will go and
keep turning until hand tight.
4. Insert the new Sleeve B and then the
new Sleeve B Spring (included in the kit) back
into the packing cartridge housing in the order
shown in Figure 15.
5. Use the Spring Cap to compress the
Spring until you are able to thread the cap back
onto the housing.
6. Follow steps 6-7 on the previous
page to re-install the cartridge.

gure 2 and reinstall uid needle assembly.
10. Adjust uid needle packing as described on
page 8 in the uid packing adjustment section.
NOTE: Some coating leakage out of the
uid tip or the rear of the spray gun indi-
cates that an adjustment of the packing
is needed for the material being sprayed.
This is not an indication of the gun failing.
This may occur upon set-up, after a
period of spraying, or when material is
changed.

PLATINUM PRESSURE FEED
Fluid Packing Adjustment
Unlike many other spray guns that require a
matched set of needles and uid tips, the DUX
Pressure Feed uses one standard needle that
is compatible with all uid tips. The packing in
all DUX spray guns is set to a predetermined
specication 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 uid needle is not seating
properly. This may be caused by dried material
in the tip or if the uid packing is too tight. If
the packing is set too tightly for a particular
material, the needle will not be able to fully seat
in the uid tip. Conversely, uid leakage at
the rear of the spray gun indicates that the uid
packing is too loose and needs tightening.
In these cases a slight adjustment of the pack-
ing has been found to stop the leak. To adjust
the packing (See Figure 3):
1. Unscrew the uid control knob and
completely remove the needle
assembly from the rear of the spray
gun.
2. Insert the Dux Packing Tool into the
rear of the spray gun.
3. Turn the uid seal nut 1/4 turn clock
wise to tighten or counter-clockwise
to loosen.
4. Lubricate the needle per lube
instructions.
5. Reinsert the needle assembly.
6. Reattach uid hose, and test.
IMPORTANT: Some coating leakage out of
the uid tip may indicate an adjustment of
the packing is needed. This is not an indica-
tion of the spray gun failing.
NOTE: Ensure spray gun is depressurized
before making adjustments.
Step 1: Remove needle assembly
Step 2: Insert screwdriver into rear of spray
gun
Step 3: Turn uid seal nut counter-clockwise ¼
turn if leaking occurs from uid tip.
Turn clockwise ¼ turn to tighten if leaking
occurs at rear of the spray gun.

PLATINUM PRESSURE FEED
Fluid Needle Replacement
As previously mentioned, the Platinum Pressure
Feed spray gun utilizes a universal uid needle.
There is no need to change the needle when
changing uid tips unless special self-cleaning
needles have been purchased. However, nee-
dles may wear over time, especially with very
abrasive coatings, and may need to be replaced
periodically.
Removaloftheuidneedle
1. Ensure the spray gun is depressurized
2. Unscrew the uid control knob and com-
pletely remove the needle assembly.
3. Remove the needle cap (# 5 in Figure 16).
4. Remove the spring and needle from the uid

The DUX Platinum Pressure Feed is provided with a brass trigger pin. This pin is manufactured from a
relatively soft metal to reduce wear on the Stainless Steel trigger.
Because it is a wearable part, it may be necessary to replace the trigger pin when heavy use of the gun
has resulted in deformation. When this occurs, it is best to replace the entire trigger pis-ton assembly,
since an excessively worn trigger pin may have caused unseen wear on other portions of the air valve.
