Double-chamber blasting machines (available in versions with capacity of lt. 50 and lt. 275) of the continuous cycle type, which operate from 1 to 4 independent outlets, without having to interrupt the blasting process to reload the abrasive.
The machine consists of two tanks joined and stacked one on top of the other. The lower tank is always under pressure, while the upper one is pressurised by solenoid valves after receiving the abrasive from the silo above it.
