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.
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.

For the best transfer efficiency, use the lowest set-
ting needed to achieve desired finish quality.
Reducing the fan air pressure to 0 psi (or fully clos-
ing the fan adjustment valve) will produce a round
pattern.
