　　(4) Imitation stone paint spray gun: suitable for spraying imitation stone paint for architectural decoration.

　　5. Large flow and low pressure spray gun (HVLP)

　　The high-flow low-pressure spray gun is composed of a feeding system and a specially designed HVLP spray gun. The power of HVLP spray gun to atomize paint is not the pressure of compressed air but the flow rate, so the pressure of paint atomization is lower than 0.07Mpa. In the HVLP system, pressure paint tanks or double diaphragm pumps are generally used for pressure feeding. Since the HVLP system has different requirements for the air supply source from the traditional air spray gun, the air supply method is usually an electric turbocharger to provide a large flow of ultra-low pressure airflow. Another common compressed air is used for depressurization.
