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,
NOTE: Reducing the fan air pressure to 0 psi
(or fully closing the fan adjustment valve) will
produce a round pattern.

reduce the fan air pressure (or slightly
close the fan adjustment valve on manifold

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.
