Basic master

Fine sandblasting unit

Fine sandblasting unit with 2 blasting tanks and large blasting chamber.

Advantages

  • Homogeneous and tension-free surfaces thanks to the special mixing chamber technology (Venturi principle), regardless of the fill level of the sandblasting tank.
  • High economic efficiency as there is no unnecessary after-flow of sandblasting material.
  • Targeted, precise sandblasting due to excellent illumination of the blasting chamber with LED technology.

Details

  • Large sandblasting chamber (20 l) allows ample freedom of movement.
  • Good, long-lasting visibility of the objects through silicone-coated glass panel (10x longer service life).
