90PSI Portable Sandblasting Tool, Air Consumption 7.0cfm, Sand Outlet Inner Diameter 6.5mm - Adjustable Gravity Spraying Tool For Rust Removal And Paint Removal, Requires Air Compressor To Operate

Specifications for a pneumatic sandblasting gun include an air consumption of 7.0 cfm, a pot capacity of 21 lbs, and three air inlet connectors. It operates at a pressure of 90 Psi and has a nozzle inner diameter of 6.5 mm (0.25 in). This sandblasting gun allows for adjustable sandblasting flow, is lightweight, and is designed for handling various small and light metal surfaces, making it suitable for spray polishing, burring, derusting, and detailed finishing.

The sandblasting procedure involves using compressed air to propel various materials, such as copper ore sand, quartz sand, emery, iron sand, and Hainan sand, onto the surface of an object at high speeds.

The interaction of materials with the workpiece surface and the cutting process can lead to a certain level of cleanliness (like rust elimination). Additionally, this can enhance the fatigue resistance of the workpiece. Sandblasting creates a specific roughness on the surface, which boosts the adhesion between the surface and the coating, prolongs the coating's lifespan, and also aids in the application and aesthetics of the coating.
