Power-Saving Attachment

For more Information


ECO-SHOCK is a revolutionary dry pump accessory that can dramatically reduce power consumption by attaching to the dry pump exhaust line.


  • Max.80% reduction of power consumption of the dry pump
  • No reduction in pumping performance
  • Simple installation


  • Dry vacuum pumps for evacuating iner gases such as air, nitrogen or argon.
  • Dry vacuum pumps used with sputtering or loading / unloading chambers.
