DA/DA-VS Vacuum Deaerator

DA/DA-VS Vacuum Deaerator


  • food (sirups, drinks, ketchup, nut butter),
  • pharmaceuticals and cosmetics (liquid soap, shampoo, toothpaste, detergents),
  • chemical products (paints & coatings, adhesives, sealants, lubricants, latex compounds).



  • removes air from products, which prevents product oxidation, decomposition of fats or off flavour and smell (products are of better quality and have longer shelf-life),
  • high throughput rates (dependent on product viscosity),
  • minimal product loss,
  • fast and easy cleaning,
  • low maintenance,
  • compact design,
  • options: special version for use in explosion risk areas, water-cooled design.


The NETZSCH Vacuum Deaerator works on the principle of vacuum – thin-film – rotary process. A suction pump creates vacuum in the deaeration chamber, drawing your product inside the unit and into the centre of a rotating bowl. Continuous deaeration is achieved by a thin product layer being formed on the rotating bowl. Product discharge from the rotating bowl is effected by centrifugal force spinning the product out through a pick-up pipe. Product dwell time in the deaeration chamber and product throughput can be varied by means of non-return valves.
