Selection Charts
Proper Needle/Nozzle Selection
The spray gun's needle/nozzle kits range in size to provide different fluid flow rates.
As a general guideline, use the fluid nozzle that will give
the required flow with the needle fully triggered at a fluid
pressure of 5-20 psi (0.035 MPa, 3.5 bar - 0.14 MPa. 14
bar)
For low flow rates or light viscosity fluid, select the
smaller nozzle sizes.
For high flow rates or high viscosity fluid, select the
larger nozzle sizes.
For thicker, abrasive fluids, hardened SST needle tips
and nozzles are recommended.
Air Caps
Gun Selection
HVLP Guns
An HVLP gun is a high transfer efficiency gun that limits
the air pressure at the air cap to 10 psi (0.07 MPa, 0.7
bar) maximum. In some areas, an HVLP gun is required
for compliance with environmental standards.
Compliant Guns
A compliant gun is a high transfer efficiency gun that has
been tested to have a transfer efficiency greater than or
equal to HVLP guns. In addition, the compliant air cap
consumes much less air than the HVLP air cap.
The Graco compliant guns have no restrictions on air
cap pressures, but the gun inlet pressure must remain
under 30 psi (0.21 MPa, 2.1 bar) to remain in compliance.
Airspray Guns
An airspray gun has excellent atomization and high production rates typically with some reduction in transfer
efficiency.
The chart below lists the air caps available for pressure
feed, gravity, and siphon feed guns.

Installation
Installation
The Automatic XT spray guns were designed to produce
the highest quality finish with today's fluids as well as
the low V.O.C. (volatile organic compound) fluids of
tomorrow.
This spray gun can spray most coatings or finishes currently being used for automotive, industrial, aerospace,
marine, wood, plastic and architectural applications,
while easily operating from paint delivery systems, such
as pressure pots or remote pumps for production line
operation.
The air regulator must have a minimum air flow capacity
of 30 scfm at 100 psi (0.7 MPa, 7 bar) air pressure.

Setup
Setup
Connect Air Line
You must install an air pressure regulator (F) on
each gun air line to control air pressure to the gun.
See F
IG. 8.
If your regulated air source does not have a filter,
install an air filter (G) on each air line to ensure a
dry, clean air supply to the gun. Dirt and moisture
can ruin the appearance of your finished workpiece. See F
Install a bleed type air shutoff valve (E) on each
gun air supply line, downstream of the gun air regulator, to shut off air to the gun.
1. For manifolds with a separate ATOM and FAN port,
the gun cylinder, fan, and atomization air must be
supplied and regulated separately. For the manual
fan valve manifold, only one supply line is required
for both atomization and fan air.
The gun atomizing and fan air inlets are 3/8 in. O.D.
tubing. The cylinder air inlet accepts 1/4 in. (6.3
mm) O.D. tubing. Use 3/8 in. (9.5 mm) O.D. tubing
for fan and atomization air to minimize excessive
pressure drop in the hoses.

Adjust Spray Pattern
Do not exceed 100 psi (0.7 MPa, 7 bar) maximum fluid
and air pressure. Higher pressures can cause parts to
rupture and result in serious injury.
The spray gun fluid flow is controlled by the fluid pressure regulator and the fluid control knob. Use the fluid
pressure regulator to adjust the general fluid flow and
the fluid control knob to make precise fluid flow adjustments.
CAUTION
Use caution when operating the fluid control valve
near the closed position. The plastic needle tip may
be damaged if forced too hard against the nozzle seat
by the fluid control valve.
Follow these steps to establish the correct fluid flow and
air flow:
1. To achieve desired flow, adjust the fluid flow using
the fluid pressure regulator (L) installed in the gun
fluid line. Typical industrial flow rates will vary with
regulator pressures from 5 to 30 psi (34 to 210 kPa,
0.3 to 2.1 bar). If the fluid pressure is too low at the
desired flow rate, install a smaller nozzle. If the fluid
pressure is too high, install a larger nozzle.
A larger fluid nozzle at a reduced fluid pressure will
maintain the same flow rate, but the fluid stream
(velocity) will slow down. When air is applied, this
allows air to act on the fluid longer and improve the
atomization.
2. Using the air pressure regulator (F), set the fan and
atomizing air supply pressure per Table 1. Use
these suggested settings as a starting point.

HVLP and Compliant Gun Limits
HVLP Guns: local laws may limit the maximum
pressure to 10 psi (70 kPa, 0.7 bar) at the air cap
for compliance. 35 psi (25 kPa, 2.5 bar) inlet air
yields 10 psi (70 kPa, 0.7 bar) at the air cap. To
measure pressure at the air cap, use the accessory
tapped air cap. See Accessories, page 33.
For spray guns equipped with the fluid control knob,
you can make flow rate changes at the spray gun.
Compliant Guns: the maximum inlet pressure to the
manifold is 30 psi atomizing air.
Rotate the fluid control knob clockwise to reduce the
flow.

3. Test the spray pattern atomization while keeping the
gun a consistent distance, about 6 to 8 inches (150
to 200 mm), from the test piece.
Check the atomization quality. Increase the gun
atomizing air supply pressure with the air pressure
regulator in 5 psi (34 kPa, 0.3 bar) increments until
you obtain the desired atomization.
For the best transfer efficiency, use the lowest setting needed to achieve desired finish quality.
4. If the spray pattern is too wide or split, reduce the
fan air pressure (or slightly close the fan adjustment
valve on manifold 288223).
To further control the spray pattern of airspray guns
only, use an alternate air cap. For a list of available
air caps, refer to Accessories, page 33.
Reducing the fan air pressure to 0 psi (or fully closing the fan adjustment valve) will produce a round
pattern.

Operation
Operation
Pressure Relief Procedure
1. Turn off all bleed type air valves and all other air and
fluid supplies to the gun.
2. Trigger the gun into a grounded metal waste container to relieve air and fluid pressure.
TI8174a
FIG. 14: Pressure Relief
To achieve best results when applying fluid:
• Keep gun perpendicular and 6 to 8 in. (150 to 200
mm) from object being sprayed.
• Use smooth, parallel strokes across surface to be
sprayed with 50% overlap.
Incorrect
TI8098a
Apply Fluid
The spray gun has a built-in lead and lag operation.
When triggered, the gun begins emitting air before the
fluid is discharged. When the trigger actuation air is
stopped, the fluid stops before the air flow stops. This
helps ensure that the spray is atomized and prevents
fluid buildup on the air cap and tip.
Adjust the system control device, if it is automatic, so the
gun starts spraying just before meeting the part and
stops as soon as the part has passed. Keep the gun a
consistent distance, 6 to 8 in. (150 to 200 mm), from the
surface of the object being sprayed.
