In this type of machine, the abrasive material, whether made of metallic grit or other, is projected against the surface by compressed air supplied by one or more nozzles.
In this case, the covered assumes a conical shape and covers an area directly proportional to the distance of the nozzle from the surface concerned.
These machines offer two great advantages: the ability to act locally on small specific areas with high concentration and the possibility to use steel grit or other abrasives indifferently.
Compressed air systems are divided into:
• suction systems;
• pressurized systems.
Pressurized systems offer the advantage of greater power and therefore a higher yield.
Our compressed air sandblasting machines (with suction or pressurized system) are suitable for different application fields, such as aerospace industry, automotive industry, metal structural work, stainless steel working, glassworks, building and road construction.
