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
