The pressure-feeding spray gun supplies paint from a separate paint booster tank (or paint pump). The pressure of the booster tank can be increased to supply paint to several spray guns at the same time. The paint nozzle of this spray gun is on the same plane as the center hole of the air cap, or slightly concave inward than the center hole of the air cap, and there is no need to form negative pressure at the front end of the paint nozzle. Pressure-feed spray guns are suitable for applications where there is a large amount of paint and continuous spraying. Internal mixing spray gun: There are two air supply systems in the internal mixing spray gun, namely the compressed air system for mixing and atomizing the paint and the compressed air system for pressurizing the paint in the paint container. The paint supply method is pressure Delivery style. The center hole of the air cap has a long olive shape, so the spray pattern is oval. This spray gun has no side air holes and auxiliary air holes, and the spray pattern cannot be adjusted arbitrarily. The spray pattern is determined by the shape of the center hole of the air cap. If you want to change the width of the spray pattern, you must replace the air cap. , The internal mixing spray gun has no spray pattern adjustment mechanism, and other adjustment mechanisms are similar to the external mixing spray gun.
