Air Assisted Airless Application of Industrial Paints

Air Assisted Medium Pressure Spray Method

 

 

 

Air Assisted Airless spray uses a combination of hydraulic and pnuematic pressure to atomize.

The method provides high productivity with an good finish.

 

Very Few Changes

AA spray guns begin to atomize by hydraulic pressure, forcing paint through a very small orifice in the nozzle (0.015 to 0.035 in).  Paint is delivered from medium pressure pumps between 500 and 2000 psi.  The paint droplets are then further atomized by low pressure air (5-30 psi) at the air cap. 

 

The process is similar to both airless and conventional methods.  Spray particles retain enough velocity to travel to the substrate, but produces less bounceback or overspray waste. This method has a 60-75% transfer efficiency.  Lower operating pressures extend spray tip and pump longevity.  Safety features are similar to airless to prevent fluid injection injuries. 

Air Assisted spray provides the high volume application and production close to that of airless.  Air Assisted Airless spray is a growing technology in industrial finishing.
