With regard to overspray, the difference between airbrush and hvlp units is the following:
Airbrush Units:
There is more 'bounce back' of the solution to targeted surface. The solution that you are spraying, the stream has more wide open and it takes 1. longer 2. more solution to penetrate the targeted surface. When it does reach that targeted surface (ie the clients skin) some of it actually doesnt settle right on, but actually bounces off (overspray)
HVLP Units have a minimal amount of 'bounce back' of the solution to the targeted surface. HVLP is 'high volume low pressure' The solution that you are spraying, the stream that it has is more centered and concentrated and it 1. hits the targeted surface faster 2. takes less solution to penetrate the targeted surface (ie the clients skin) much of the solution that hits the skin actually stays and does not bounce back. The reason for this is because of the difference in air pressure and flow.
(Ive had many discussions with regard to the differences of both systems w/ body shop repair men. The reason why body shops use hvlp?! It paints better, less overspray, paints the surface smother faster and more accuratley, and takes less time and paint to do so.)
