1. Place the Air Cap in the vertical position and spray three or four horizontal patterns on a test piece.
Spray and hold the pattern in the same position until material builds-up and then release the trigger —
this is the only time in finishing that you’ll ever want to see a run or sag!
2. Inspect the pattern. If the material is sagging evenly across the pattern, start spraying, otherwise
consult the chart below.

Coating is running/dripping from
extremities of pattern and/or pattern is in

Always test application speed, spraying distance, pattern size, film thickness and finish on a test piece.
THE VARIABLE SPEED CONTROLLER (VSC)
Most coatings do not require maximum air volume to be atomized. All Turbinaire systems equipped with a
VSC have a three way power switch: On/Off/On. When the switch is in the “up” position, the turbine will
operate at maximum air volume. When the switch is in the “middle” position, the turbine is off. When the
switch is in the “down” position, the VSC can be used.
The VSC allows you to adjust the air output of the turbine based on the material being sprayed – increase
air output for heavy bodied material (i.e. latex paint) and decrease air output for light body material (i.e.
stain). Using the VSC properly will reduce overspray and increase transfer efficiency, especially with light
body material like stain, shellac and wood finishes.
To use the VSC, press the power switch in the down position, turn the VSC control knob to MAX.
While spraying a test piece, slowly turn the VSC control knob counter-clockwise to gradually reduce the
air output as much as possible without affecting the desired coating thickness and finish.
You are now ready to begin spraying!
