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).
