Multiple Advantage Pneumatic sandblasting gun is used for sandblasting polishing, metal rust removal, detail dressing, etc.Suitable for Large capacity feed pot, the sandblasting machine is suitable for all kinds of sand, black steel jade, emery, spinach beads, etc.Functional effect The sandblasting machine adopts thickened galvanized nozzles, smooth inner walls , low resistance, fast blasting speed and even sand flow.Well-designedThe sandblasting gun is a non-slip handle which conforms to the ergonomic design, has a comfortable grip, an aluminum alloy trigger aluminum, a high hardness steel valve core, easy to operate.Wide range of uses Pneumatic sandblasting gun is widely used in areas such as residue, derusting, parts renovation ancient, cleaning impurities at angle m ort, atomization, deburring, waxing, carbon, welding slag, paint or wear marks etc.Specification:Capacity: 21 lbsSpray hole diameter: approx. 6.5mm / 0.3inAir pressure: 90PSIAir consumption: 700cfmHandle size: approx. 45 x 25mm/1.8 x 1in Nozzle inner diameter: approx. 6.5mm/0.3inch Nozzle outer diameter: approx. 7mm/0.3in, 13mm/0.5in Nozzle length: approx. 67mm/2.6inchUses: Used for detail finishing such as spray polishing, burrs, rust removal, etc. of various metallic materials in corners and dead surfaces.Abrasive blasting: It uses compressed gas to pulverize the blasting material (common pulverizing materials are copper ore sand, quartz sand, sand emery, iron sand, Hainan sand, etc.) on the workpiece surface. Under the effect of impact and cutting, the surface can get a certain degree of cleanliness (such as rust removal), at the same time, it also improves the fatigue resistance of the workpiece; sandblasting will give the surface a certain roughness, which increases its Adhesion between coatings prolongs the durability of the coating film, and is also conducive to smoothing and decoration of the coating.
