Air Spray
Process
Paint is drawn into the gun by venturi
and is a atomized by injected air. The
fan can be manipulated by air
introduced around the fan. Because
the paint is both picked up and
atomized by air the paint leaves the
nozzle in form of a fine mist. The paint
droplets are suspended in the air and
tend to float, causing overspray. The
transfer efficiency is very low, only 25-
45% of the coating reaches the job
Advantages
• Adjustable air control
• Adjustable fluid control
• Fan width adjustment
Disadvantages
• Poor transfer efficiency
• Overspray
