The complete solution for vacuum generation.


Our vacuum screw packages are equipped with a specially-developed Kaeser vacuum airend with SIGMA-Profile. Single-stage vacuum generationsupplies a so-called low vacuum. We offer three series with these technical data:

  • Intake capacity: 4.75 to 15.70 m³/min
  • Final vacuum: 99 %
  • Pressure: 10 mbar (a)

The connection-ready packages are the solution for dust extractionpackaging and filling machinesdryingdegassing or filtration, for example.

Your advantages

  • Extremely efficient: 
    IE3 motors are mandatory in the EU since 2015. These motors and the SIGMA profile ensure that our packages use significantly less power.
  • Low-maintenance and service-friendly: 
    Cooling air filter mats protect the interior from dirt, the gas ballast provides enhanced water vapour tolerance, low speeds extend the service life of all components. 
    Wide opening doors and a removable rear panel facilitate maintenance.
