HVLP paint sprayers have greater transfer efficiency because using the lower pressure results in less viscosity of the particles. They are also safer because there is a reduced chance of injecting paint in an accident. Waste also is significantly reduced.
These guns also have fewer maintenance needs because of the lower pressures that are involved. With the attached regulator, you have greater control over your HVLP paint gun. These guns are also the greener choice because they cause less waste than do conventional paint guns.
