It is a real style of environment-friendly, paint-saving spray gun, with various advantages: reduce splashing and bouncing through the application of high flow, low pressure technology; increase paint adhesion; save material for the transfering efficiency above 20-30% over traditional spray gun. Air cap and air line construction are both improved too, to optimize the inner pressure distribution and for the first-class pulverization function. Alternative digital to control pressure handily and accurately. Can freely pick pressure value between 20psi and 40psi to be at sufficient optimal performance. Detect each piece of spray gun 100% manually to ensure a constant high quality of each piece of spray gun and replaceable nozzle kit. It is of good cost performance, the best substitutes of the one in same industry for you.
