In a high pressure paint spray gun, pressurized air is fed through a hose and into a chamber where it is combined with paint and expelled through a nozzle. The force of the pressurized air allows the paint to spray in a fine mist so it can quickly and efficiently coat a surface. The pressure of the air is adjustable to give the user more control over the spray pattern, the thickness of coat, and other factors. In addition, the spray gun comes with various nozzle sizes and shapes that can be used depending on the project.
