Google HVLP.
Hi.
There seems to be confusion about the meaning of HVLP.
HVLP technology was introduced several decades ago to quantitatively improve the transfer of paint from the gun to the piece to be painted.
The system uses a large amount (HV) of low pressure (LP) air in order to reduce the overspray intended as a nebulized product dispersed in the air and at the same time the rebound product, all to minimize waste and therefore the emissions of VOCs in the atmosphere.
The result is that if (hypothetically) a traditional system allows less than 40% of the sprayed product to be transferred to the piece to be painted (the remaining 60 is dispersed in the air), this percentage can rise to 70% or more with an HVLP system with a good set-up
The above does not mean that with an HVLP system I will put more paint on my plane, but that I will waste less.

P.S.: exactly what Kevin meant
