Vacuum Technology
Liquid jet ventilators
Liquid jet ventilators type fv1 are based on proven jet pump technology and often used to draw off air, gases or vapor.
Applications
Liquid jet ventilators are used to draw off air, gases or vapor.
They are designed to suck in gas flows at small pressure differences. The pressure gain (compression) which these units can archive is in the range between 1 and 20 mbar.
Mode of operation
Liquid jet ventilators operate on the jet pumps principle. Their action is based on the jet of motive liquid which emerges from the motive nozzle entraining and conveying the surrounding gas.
The specific motive liquid requirement in m³ of liquid per m3 of air or gas:
- Decreases with higher motive liquid pressure p₁
- Increases with rising, required compression ∆p
- Is independent of nature and density of the drawn off gases.
Advantages
- With correct choice of materials of manufacture an almost unlimited life
- Maintenance-free
- Quickly and simply brought into operation
- Can be fabricated from many different materials
- Low capital and installation costs
- Low-noise operation
- No moving parts

Around the world in seven questions: New foods we’ll love
Last year was not a year of hyped-up headlines for alternative proteins. Perhaps that is precisely why it was an important year for food biotech, the biotechnology behind everyday foods and ingredients. While the sector worked through a difficult funding environment, approvals were still granted, pilot lines set up and new platforms tested in the background. In short: headlines are turning into infrastructure. Frederieke Reiners heads GEA’s New Food business. She and her team work at the intersection of biotechnology and industrial food production. In this interview, she takes us on a world tour of food biotech in seven questions.
