HVLP and gravity guns

They are not the same thing, pot location is the common thing, but they use far different pressures and act different when used. I'm sure someone with more knowledge will explain the difference better than me.

Gravity gun just means the cup is on top and the paint flows into
the gun by gravity.

HVLP means High Volume Low Pressure-(they take a lot of air "volume")
They spray at a lower pressure at the tip-usually around 12 psi,
(The gun's inlet pressure is much higher, the gun itself lowers it at the tip)

Although most HVLP's are gravity,
HVLP and Conventional guns come in both gravity and siphon cups.

HVLP is 3-10 psi at the tip, at least for the seta's we use. Not all HVLP's are gravity feed, and not all gravity feeds are HVLP. Most tend to be, but.

Here, you must use a HVLP gun (50% transer rate or better), or one which achieves similar transer efficiensty. The gun will say if it's HVLP or not.
