Spray Gun Overview
The air assist spray gun combines the airless and air spray concepts.
Airless and air assist spray:
• Hydraulic force pushes high-pressure fluid through
the spray tip orifice.
• The spray tip shapes the fluid into a spray pattern.
The fluid flow and pattern width depend on the size
of the spray tip, the fluid viscosity, and the fluid
pressure. See Spray Tip Charts, page 50.
Air assist spray:
• Air from the air cap further atomizes the fluid and
completes the atomization of the paint tails into the
pattern to produce a uniform pattern. Air caps
optimize the finish quality for different coating
properties. Multiple air caps are available to meet
various finishing needs. See the Air Cap Selection
Guide, page 54.
• The fan adjustment knob can adjust the width of the
pattern.
• The air assist spray gun has a different pattern
width adjustment procedure than an air spray gun.
• Pattern width is decreased by using more air.
• Pattern width is increased by using less air or using
a larger spray tip size.
The spray gun has a built-in lead and lag operation.
When triggered, the gun emits air before the fluid
discharges. When the trigger releases, the fluid stops
before the air flow stops. This helps ensure the spray
atomizes and prevents fluid buildup on the air cap.
