I am sorry to disagree, but true HVLP spraying with a three or four stage turbine is so far beyond the capability of compressor spraying I can only assume you where using an inferior HVLP system, the difference between the two is very convincing, I think the whole HVLP system concept is bourne out by compressor spray gun companies trying to convince us that they can compete and bringing out what they call compatable guns, they can't its a completly different concept, any compressor gun that is supposedly HVLP compatable that I have used has so much bounce back in comparison I may as well have used a compressor gun.

Mike I think you should go and revise your research into HVLP. You seem to be blinkered to the issue in your belief that the turbine systems are the only HVLP. They are not.
Is your understanding of HVLP correct?
Do you realise the whole HVLP matter refers to the air cap pressure and the delivery of the materials?
I'm beginning to wonder if you have a tie to a manufacturer.
To be classed as HVLP the gun has to be able to produce a useable spray pattern at 10psi or lower. A compressor based system achieves this by it's internal design, thus giving it the ability to produce sub 10psi at it's air cap.
It's input pressure may be 25-30-35-40psi but its design enables the previously mentioned "magic" numbers.
If you, Mike, are ever up my way I will gladly take you to a professional spray shop and demonstrate "true HVLP" on a compressor based system. Just let me know.
To anyone else interested, turbines are not the be all and end all of HVLP spray painting. Go read the manufacturers data and literature.
The turbine systems are a HVLP solution, and some are very very good, but you won't run a nailer off one. My advice look at and read all you can find, but do not discount compressers on the HVLP painting issue alone.
That's it now, I'm done. Sorry OP, just getting a little p'd off with disinformation.
