A specialized spray application device utilizes a separate container, typically a tank, to hold a substantial volume of coating material. This reservoir is pressurized, forcing the paint or other finish through a hose to the spray gun. The air pressure within the tank directly propels the fluid, ensuring a consistent flow rate to the nozzle, independent of gravity or siphon action. An example of its application is in high-volume manufacturing, where continuous and even coating of products is essential.
This type of system offers several advantages, including the ability to handle viscous materials more effectively than siphon-feed or gravity-feed guns. The pressurized feed system also permits longer, uninterrupted spraying sessions due to the larger paint capacity. Historically, these systems played a critical role in the automotive industry, enabling efficient and uniform application of coatings to vehicle bodies. This technology improves finish consistency, reduces operator fatigue, and minimizes material waste.
