Anyone used a turbine HVLP spraying system to paint their car? Some of the results look good. The Fujispray and Apollo systems look good so too the TP tools one though not available in Oz

Quote from one experienced painter: “the only difference between a turbine system and a conventional system is THE COMPRESSOR METHOD. The conventional system uses a conventional compressor which is large enough to keep up with the demands of an HVLP gun (which requires quite a bit more volume than a conventional gun). The HVLP turbine system replaces the large conventional compressor with a small electric turbine motor which produces the same exact pressure at the gun. Therefore, there is ABSOLUTELY NO DIFFERENCE between conventional HVLP spraying and HVLP turbine spraying, except that the turbine is actually a better method because it dries the air before delivery AND you never have to wait for a conventional compressor to "catch up" in the middle of a paint job AND you can never have an oil contamination problem because there is no oil in an electric turbine motor. When spraying a car, things have to be just right. Air temperature and the purity of the air must be as clean and pure as possible. Why complicate matters by using a standard compressor which will only introduce oil and water into the picture? Two things you absolutely NEVER want when spraying a car. Given the choice between the two, I'd choose an HVLP turbine system every single time.

A turbine HVLP system is absolutely NOT the same as a compressor-based system and any attempt at using it in the same way will certainly result in disaster. Your mix requires about 10-15% more reducer than with a conventional gun and you work a bit closer to the surface than you would otherwise. Once you learn how to use the system it is absolutely amazing how efficient and clean it is. Transfer efficiency is usually better than 80% and there is almost no overspray whatsoever”

I know precisely d1ck all about spray painting. For sound advice ask Phat Kat who mostly hangs out on http://forum.minidriver.com.au/index.php these days.

What I do know is that the statement quoted is not correct. Compressing air makes it hotter. When hot and compressed it can hold the mosture it held when cool and not compressed. If you cool the compressed air the mositure condenses out (because the saturation limit is reached). That's why commercial compressor systems can have refrigerant dryers. A high pressure compressor system has the potential, if correctly cooled and separated, to have lower moisture at the gun than a low pressure system which removes none of the moisture.

If your supply hose is where the compressed air is cooling, then you will have water at the gun.
