The air-assisted spray gun combines airless and
air spraying concepts. The spray tip atomizes
and 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.
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
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:
NOTE:
NOTE: For airless atomization, if desired, turn the
gun’s atomizing air adjustment valve completely off.
Closing this valve does not affect alternator operation.
