Applications Used in continuous drainage for fine adjustment of vacuum by means of water column’s height. With an integrated control valve. Available as a plug-in unit for direct connection to a vacuum outlet or as a rail-mounted unit, NIST inlet. The vacuum is enabled via the integrated control valve and the suction needed for suction is generated. As soon as air bubbles become visible at the lower end of the immersion tube, the low pressure set via the immersion tube has been reached. If no vacuum is available, it can be generated via an ejector from compressed air. See under Woodpecker regulators.
