Features of ZJ Series High Vacuum Pumping System

  • GIS connection available
  • Digital vacuum degree management
  • Anti-absorption
  • The machine can start fast
  • Strong vacuum pumping capacity
  • Stable performance
  • Easy operation

There is a combination of axial fan and condenser to deal with moisture and gas from the vacuum pump and roots pump. It can prolong the time to change vacuum oil while meeting emission standard

As a manufacturer, YUNENG also offers many types of vacuum pumping systems.
