The equipment adopts an integrated structure design. The whole machine is integrated into a single machine from a sand blasting chamber, a pressure tank, a dust collector, an electric box, etc., with a small footprint and convenient transportation. The operation of the whole machine is simple and convenient. Connect the air source to adjust the blasting pressure, start the 220V power supply and the fan, hold the spray gun at the surface of the part, and press the blasting foot switch at the same time to clean the surface of the part. The foot switch and the pressure tank system are in a linked state. When the blasting operation is performed, the tank is aerated and closed. When the blasting is stopped, the tank is exhausted and the shots are automatically added.
