Air Flow Adjustment
In most applications using the round spray kit, it is
desirable to use a very low air flow through the air
cap while maintaining enough pressure at the gun
inlet for full electrostatic power (about 40 psi [0.3
MPa, 2.8 bar]). Use the gun’s atomizing air restrictor
valve to restrict the air cap air. The fan air adjustment
valve can be used to adjust the pattern size from 4
to 8 in. (102 to 204 mm).
