How the Electrostatic AA Spray Gun Works

WARNING

Skin 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 completes the atomization of the fluid tails to produce a uniform pattern.

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

Operating the Spray

Function

Applying a minimum of 50 psi (0.35 MPa, 3.5 bar) air pressure to the gun manifold’s cylinder air fitting (CYL) will retract the gun piston, which opens the air valves and a short time later opens the fluid needle. This pro- vides the proper air lead and lag when triggering the gun. A spring returns the piston when the cylinder air is shut off.

Operating the Electrostatics

To operate the electrostatics, apply air pressure to the gun manifold’s turbine air fitting (TA) through a Graco grounded air hose. The air enters the manifold and is directed to the inlet of the power supply turbine. The air spins the turbine, which then provides electrical power to the internal high voltage power supply. The fluid is charged by the spray gun electrode. The charged fluid is attracted to the nearest grounded object, wrapping around and evenly coating all surfaces.

The turbine air is exhausted into the shroud and out the back of the manifold through the exhaust fitting (EXH). The exhaust air helps keep contaminants out and helps keep the gun clean.

Gun Features and Options

•The gun is designed for use with a reciprocator, and can be mounted directly on a 1/2 in. (13 mm) rod. With additional brackets, the gun can be mounted for robotic applications.

•The gun’s quick-disconnect design enables its removal without disconnecting the air lines to the gun.

•Gun functions are activated from a separate control- ler that sends the appropriate signal to the actuating solenoids.

•The optional fiber optic readout system can be installed to monitor the gun’s spraying voltage. A fiber optic cable connected to the gun manifold car- ries the signal from the gun to a remote display module. Part No. 224117 Display Module displays the gun’s spraying voltage and current. Bat- tery-operated Display Module 189762 displays the gun’s spraying voltage only.
