Operation

How the Air-Assisted Airless Spray Gun Operates

The

air-assisted airless 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 paint tails into the pattern to produce a more uniform pattern. The pattern adjustment valve controls the width of the pattern.



When spraying at fluid pressures below 500 psi (35 bar) or spraying light viscosity fluids, use optional fluid needle 220–413 (see page 20). The standard needle may not provide positive shut of pressures or for such fluids.



When spraying acid catalyzed varnishes, use optional fluid needle 222–497 (see page 20). Using a standard needle may decrease needle life and leakage may occur

f at those

Note that the air-assisted airless spray gun dif an air spray gun in that increasing the pattern air reduces the pattern width. To increase the pattern width, less pattern air or a larger size tip must be used.

The spray gun has a built-in lead and lag operation. When triggered, the gun begins emitting air before the fluid is discharged. When the trigger is released, the fluid stops before the air flow stops. This helps assure the spray is atomized and prevents fluid buildup on the air cap.
