How the Electrostatic AA Spray Gun Works
This is not an air spray gun. To help prevent serious injury from pressurized fluid, such as skin injection, and splashing fluid, read and follow the Skin Injection Hazard Warnings on page 5.

As the gun is triggered, part of the regulated air operates the alternator turbine and the rest of the air helps atomize the fluid being sprayed. The
Gun Overview
alternator generates power, which is converted by the power cartridge to supply high voltage to the gun’s electrode.
The fluid is electrostatically charged as it passes the electrode. The charged fluid is attracted to the grounded workpiece, wrapping around and evenly coating all surfaces.
The regulated air that is directed to the air cap can be further controlled using the gun’s atomizing air adjustment valve. This valve can be used to restrict air flow to the air cap while maintaining sufficient air flow to the alternator. The atomizing air adjustment valve does not control pattern width. To change pattern width, use a new tip size, or use the fan adjustment to narrow the pattern width.
The high working fluid pressure of this gun provides the power needed to atomize higher solids materials.
NOTE: For airless atomization, if desired, turn the gun’s atomizing air adjustment valve completely off. Closing this valve does not affect alternator operation.
