How the Electrostatic AA Spray Gun Works

WARNING

Fluid Injection Hazard

Remember, this is not an air spray gun. For your safety, read and follow all Warn- ings in this manual.

The air-assisted spray gun combines airless and air spraying concepts. The spray tip shapes the fluid into a fan pattern, as does a conventional airless spray tip. Air from the air cap further atomizes the fluid and com- pletes the atomization of the fluid tails to produce a uni- form pattern.

As the gun is triggered, part of the regulated air oper- ates the turbine and the rest of the air atomizes the fluid being sprayed. The turbine generates power, which is converted by the power cartridge to supply high volt- age current to the gun’s electrode.

The regulated air that is directed to the air cap can be further controlled using the gun’s atomizing air adjust- ment valve. This valve can be used to restrict air flow to the air cap while maintaining sufficient air flow to the turbine.The atomizing air adjustment valve does not control pattern width. To change pattern width, a new tip size must be used.

The high working fluid pressure of this gun provides the power needed to atomize higher solids materials.

The gun’s internal power supply provides high voltage current. 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.

NOTE: For airless atomization, if desired, turn the gun’s atomizing air adjustment valve completely off. Closing this valve does not affect turbine operation.
