Where are degassing processes employed?
In many industries the degassing of liquid, paste-like and moist products is one of the most important applications of modern vacuum technology. Gases, vapours and moisture are extracted under vacuum from the processed material, improving product quality.

The degassing of plastics during extrusion is an example: vapourised moisture and gases driven off by the melting process are extracted directly from the extruder screw zone, significantly improving the structure and physical properties of the product.

We offer a standardised range of vacuum pump systems designed specifically for extrusion processes, which include separator/filter units to condense the extracted vapours and gases. Our project engineers will calculate your requirements and recommend a system precisely matched to your extruder throughput and raw material.

We offer vacuum solutions for all degassing processes. Our customers rely on our high quality products and decades of experience in all areas of degassing. For degassing applications in the food production industry we offer a wide range of vacuum pumps, which can be optimised for any process and meet the highest hygiene standards.

One area in which vacuum systems are subject to special requirements is steel degassing: the high vapour/gas temperatures and elevated dust levels present particular problems. Our systems can operate in this hostile environment, as they are completely dry running and use the latest technology. The energy efficiency levels of our systems are superior to those of our competitors.


Examples for the use of Busch vacuum technology in degassing:


  1. Deaeration of Pastes and Moist Materials – Food Production
  2. Degassing of Plastics – Plastics Extrusion
  3. Degassing of Steel – High Quality Steel Alloy Production
  4. Deaeration of Seawater – In Oil Production
  5. Deaeration of Mineral Water – Beverage Production
