HVLP paint sprayers commonly known as air paint sprayers are spray guns that use compressed air to atomize the paint particles and with the pressure of the air, the gun applies an even layer of the paint on the desired surface. HVLP stands for High Volume, and Low Pressure and this paint sprayer uses low pressure to paint the surfaces.
