The Unical 9000(X) is operated with an external air pressure of (4)* … 10 bar.
Adjust the pressure regulator so that the operating pressure for the retractable
fitting is kept within 4 and 7 bar. The air must be condensate- and oil-free.
Maximum air consumption during probe activation is 300 liter/min.
The connector for the compressed air supply is located behind the filter / water
trap. It has a G 1/4” female thread and accepts tubes with an inside diameter of
6 mm (preferably flexible). We recommend using the ZU 0656 connection kit.
* Increased minimum pressure required in the case of high process pressure or
difficult process media
