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.
