A sandblasting machine is used in industrial applications for removing old paint, rust, and oxidation. The process is used to clean up a surface and is a cost-effective alternative to mechanical grinding. The sandblasting machine is powered by a good air compressor, which produces up to 800 litres of air per minute. It can remove three to four square feet of material,and requires an electric connection of at least 12 volts.
