This is a turbine HVLP system. HVLP systems are categorized by the number of fans they use, more fans mean higher air pressure which is measured in pounds per square inch (PSI). So a 3-stage turbine (what we have) uses three fans, generating 7psi. 
A turbine HVLP Spray Gun is an independent system that utilizes a turbine to generate the volume of air that an HVLP Spray Gun requires to spray. The turbine draws sufficient air into the unit which is then transferred through the hose which provides the air needed for atomization.
 
A compressor fed HVLP Spray gun utilizes compressed air generated by the air compressor to feed the required volume of air to the spray gun. Our turbine system doesn’t need a compressor. It’s extremely powerful and sprays our OHE straight out of the can.
