Atomizing Air Pressure 1
See Figure 2. Atomizing air pressure 1 (2) is added to the powder and
air stream to increase the powder velocity in the diffuser and to break up
clumps of powder.
Atomizing Air Pressure 1
Results
Too low
Powder flows heavily and inconsistently
Too high
Powder velocity increases, causing
excessive overspray, impact-fusion, and
premature wear of the pump and gun
parts
Increasing the atomizing air pressure decreases the powder flow rate of
some pumps, requiring minor adjustments in the flow-rate air pressure
setting to maintain the same powder flow rate.
Atomizing Air Pressure 2
See Figure 2. Atomizing air pressure 2 (5) is added to the powder to
increase the powder velocity through the gun. The higher the flow rate,
the higher the charge and wear on gun parts.

1. Turn the control unit power switch OFF. The solenoid valve closes
and shuts off air to the pump and gun. If you are using auxiliary air,
turn the regulator counterclockwise until the gauge reads zero.
2. Perform the daily maintenance procedures described in
Maintenance.
