Seperate dispersing unit and control unit , pressure-resistant up to 3 bar overpressure, optional vacuum operation from 300 mbar (absolute pressure)

Still have questions?


This device disperses particles at positive pressure values of up to 3 bar. Dispersing unit and electronic control unit able to be set up separately at a distance of up to 2 m from each other

In addition, the return speed is very fast when switching out reservoirs. It is approx. 1 minute.

Optional operation with low pressure from 300 mbar absolute is possible (please see accessories).

Please note: The feed stock reservoirs with a diameter of 7, 10, 14 or 20 mm are pressure-resistant.

For operation with low pressure special pressure-resistant feed stock reservoirs are needed. Their piston is strongly connected to the feeding unit by a claw. This enables an undisturbed operation with low pressure. Old RBG models can be upgraded with this function by Palas®.

The feed stock reservoir with a diameter of 28 mm is not pressure-resistant, but can be used with the RBG 1000 ID under atmospheric conditions.

Nitrogen cannot be used as the dispersing gas in the pressure-resistant version of the RBG 1000.
