[0002] A paint spray gun is a spray tool specifically designed for painting. It's widely used in a variety of fields, including painting, model making, furniture restoration, automotive painting, and handicraft painting. It uses the rapid release of liquid or compressed air as power to atomize and evenly spray the paint onto the workpiece surface. Depending on the power source and purpose, paint spray guns can be divided into various types, including standard pressure spray guns, pressurized spray guns, pressure spray guns, Carle spray guns, and automatic recovery spray guns.
