1 Features

This precision fine blasting unit of the Wassermann-brand offers you the highest quality

and most advanced technology.

This 2-chamber-unit is perfect for sand-blasting, roughening and polishing. The unit works

precisely and requires little maintenance. The entire system is continiously under pressure

and is therefore always ready for use. The relation between air and the blasting material is

set at the factory. It is determined by the size of the drillings. Adjustment of the abrasive

pressure is done by using the pressure reducer at the rear. This set discharge velocity

determines the outflowing amount of blasting media (while the relation is kept optimal and

constant).

This unit is equipped with a plug socket (power consumtion: max. 8 A).
