Alumina sandblaster (Double pen)

1. Sand blasting treatment of outer crown bracket. 2. Aluminum alloy sand cylinder, safe and durable. 3. The sand production is uniform and the mixing ratio of gas sand is good. 4. The minimum pressure can be operated from 0.1mpa to 0.8mpa. 5. Sand production Angle of 45 degrees of material stress surface is the best. 6. Solve the old sand cylinder uneven, suddenly big or small, sand blocking and blasting cylinder problems, reduce the intake joint sand joint and other parts loss. 7. Double cylinder double pen design saves the trouble of replacing abrasive and improves work efficiency.
