NETZSCH DA / DA-VS Vacuum De-Aerator

Remove micronized Gas and Air Pockets with the NETZSCH Vacuum De-Aerator

In the NETZSCH Vacuum De-Aerator, micronized gases are removed from fluids with a wide range of viscosities. By means of the VTR Principle (vacuum – thin-film – rotary process), it is possible to process products from offset ink and shampoo, for example, to a wide variety of free-flowing compounds. The throughput is product and viscosity dependent and can range from 500 to 4000 kg/h. This machine can be used to de-gas both small quantities, from interchangeable tanks in batch operation, and large batches in continuous operation.



  • Vacuum draws the product into the de-aeration chamber and directs it to the center of the rotating plate
  • The resulting thin layer of product on the rotating de-aeration plate is continuously de-gased
  • The product is discharged by centrifugal force via an outlet pipe
  • The residence time of the product in the de-aeration chamber is controlled by non-return flaps and valves
  • High throughput rates
  • No charging pump required
  • Flexible batch sizes
  • Maximum product yield
  • Easy to clean
  • Low-maintenance
  • Easy operation
  • Compact design
  • Components that come in contact with the product are made of stainless steel


  • explosion-proof model
  • full stainless steel model

NETZSCH Vacuum De-aerator for continuous and discontinuous de-aeration of the most varied fluid products


NETZSCH De-Aerator




As the global leader in particle-reduction machinery, NETZSCH offers the technology and machinery to provide true drug development solutions.


When processing liquid to high viscosity products, air or gas pockets often cause difficulties. The embedding of air and therefore oxygen can lead to negative effects on a product. In contrast, de-aerated products are more chemically dense with great shelf life.
