Pressure Regulating Station 684NGA (O2/other technical gases)


Pressure regulating station for the central gas supply up to 75 m³/h, automatic changeover

Operation / Usage:
The pressure regulating station automatically ensures continuous gas supply and control of a pipeline, which is connected with pipeline outlets and reduces the risk of accidents.
A supply by single cylinders is not available.
