Compressed air spray guns are tools that use compressed air to spray liquids, such as paint or cleaning solutions. They are commonly used in various applications, including automotive painting, woodworking, and industrial cleaning. The gun consists of a nozzle, trigger, and a reservoir for the liquid, allowing for a controlled and even application. These spray guns can be powered by an air compressor, which provides the necessary pressure to atomize the liquid into a fine mist. This makes it easier to cover large areas quickly and achieve a smooth finish. Proper maintenance and safety precautions are essential for effective and safe use.
