Sames Airspray® Technology
Airspray is commonly known as the low pressure spraying technology and operates up to 24 bar. It guarantees a high finishing quality with limited flow rate (generally under 600 cc/min).
For higher atomizing paint pressures, painters can go to the Airmix® technology with medium pressure giving a high finishing quality for high productivity requirements or the Airless technology with very high flow for very intensive production which does not request such high a quality of finishing.
The electrostatic field can reach 100,000 V with a very low current (approximate value of 100 µA in internal charge).
It is created by a low voltage generator, providing a signal to a high voltage transfomer, called an High Voltage cascade.
This effect can be used for liquid & powder paints in spray guns (Airspray or Airmix® technology) & rotary bell atomizers.
Sames Airspray® Spraying Technology Excellence
Vortex
The Vortex produces a swirling effect to the paint which allows the paint to leave the nozzle under an helical pattern shape which improves the homogeneity of the film build.
Restrictor
The restrictor calibrates the flowrate and create a controlled pressure loss in the gun upstream
Flowmax®
Flowmax® technology guarantees total sealing for leak free pumps.
Magnetic assistance
The magnetic assistance is a gun innovation to reduce the trigger stress. A magnet at the end of the stroke attracts the needle when the trigger is pulled to reduce the trigger pull up to 20%
Sames Airspray® Spraying Technology Type
Conventional (previously HPA)
This is traditional Airspray technology, able to spray viscous material (>40 s CA4) and offering the highest finishing quality
HVLP – High Volume Low Pressure (previously HTI - HVLP) :
Following a Californian rule from 1972, it was stated that the maximum air pressure at the aircap should be 0.7 bar/10 psi giving lower paint motion and a minimum of 65 % transfer efficiency.
LVLP – Low Volume Low Pressure (previously HTI)
It is a hybrid technology between the HVLP and Conventional. It combines high spraying quality while
insuring high transfer efficiency. It is recommended for medium viscosity (between 20 to 40 s CA4).
