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.
