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. See the Air Cap
chart, page 7, for maximum inlet pressures.
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. Graco
compliant guns have no restrictions on air cap
pressures. See the Air Cap chart, page 7, for
maximum inlet pressures.
Conventional Guns
An airspray gun has excellent atomization and
high production rates typically with some
reduction in transfer efficiency.

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 trig-
gered at a fluid pressure of 5–20 psi
(0.035–0.14 MPa, 0.35–1.4 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 abrasive fluids, the high wear gun mod-
els are recommended.

Air Flow
See the chart to determine air consumption. Add the air consumption values shown for the atom-
izing air and fan air pressures to get the total air consumption. For example, air cap 24B544 with
20 psi atomizing air pressure uses 3 scfm atomizing air. A 30 psi fan inlet pressure adds 5 scfm
fan air for a total of 8 scfm air consumption.

Connect Air Line
NOTE:
• You must install an air pressure regula-
tor (F) on each gun air line to control air
pressure to the gun. See FIG. 6.
• 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 FIG. 6.
• Install a bleed type air shutoff valve (E)
on each gun air supply line, down-
stream 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 atomi-
zation air must be supplied and regulated
separately. For the manual fan valve mani-
fold, only one supply line is required for
both atomization and fan air.
NOTE: 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 atomiza-
tion air to minimize excessive pressure drop in
the hoses.
2. Connect each air hose (D) to a regulated
air supply line (H).
Connect Fluid Hose
NOTE:
• Before connecting the fluid line, blow it
out with air and flush it with solvent. Use
solvent that is compatible with the fluid
to be sprayed.
• Install a fluid regulator (L) on the fluid
line to control fluid pressure to the gun.
• Install a fluid shutoff valve (M) to shut off
the fluid supply to the gun.
• Filter the fluid line of coarse particles
and sediment to avoid clogging the fluid
nozzle and causing finishing defects.
Inline fluid filter 24B707 is available.
See Accessories, page 34.
1. Connect the fluid supply hose (J) to the gun
fluid inlet (S), 1/4 npsm thread. See FIG. 8.
2. Connect the other end of the fluid hose (J)
to a regulated fluid supply outlet (M).
3. In a circulating system, connect a
grounded fluid return hose to the gun fluid
outlet (T). See FIG. 8.
In a non-circulating system, remove the
gun fluid outlet fitting (T) and plug the outlet
port with the pipe plug supplied. See FIG. 8.

Adjust Spray Pattern
Use the fluid pressure regulator to adjust the
spray gun fluid flow. Some models are
equipped with a fluid control knob to make pre-
cise fluid flow adjustments.
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 indus-
trial flow rates will vary with regulator pres-
sures 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 noz-
zle. If the fluid pressure is too high, install a
larger nozzle.
For spray guns equipped with the fluid con-
trol knob, you can make flow rate changes
at the spray gun. Rotate the fluid control
knob clockwise to reduce the flow.
NOTE: 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, the lower velocity allows
the air to act on the fluid longer, which
improves 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.
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.
NOTICE
Use caution when operating the fluid con-
trol knob near the closed position. The
plastic needle tip may be damaged if
forced too hard against the nozzle seat by
the fluid control knob.

NOTE: 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. See the table on page 7
for maximum HVLP/Compliant manifold inlet
pressures. To measure pressure at the air cap,
use the appropriate HVLP Pressure Verifica-
tion Kit. See Accessories, page 34.
Compliant Guns: See the table on page 7 for
maximum HVLP/Compliant manifold inlet pres-
sures.
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.
NOTE: 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 air-
spray guns only, use an alternate air cap.
For a list of available air caps, refer to
Accessories, page 34.
NOTE: Reducing the fan air pressure to 0 psi
(or fully closing the fan adjustment valve) will
produce a round pattern.

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 pres-
sure.
Apply Fluid
The spray gun has a built-in lead and lag oper-
ation. 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 auto-
matic, so the gun starts spraying just before
meeting the part and stops as soon as the part
has passed.
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 sur-
face to be sprayed with 50% overlap.
