Gravity feed spray guns are commonly used for their simplicity and efficiency in applying coatings and paints. In these guns, the paint or coating material is supplied to the spray nozzle by gravity from a container mounted above the gun. This design allows for a direct and smooth flow of material, reducing the chances of clogging and providing better control over the spray pattern. Gravity feed guns are particularly advantageous for smaller, detailed work where precision is important, as they can achieve a fine and consistent finish with less effort compared to other feeding methods.
