Vacuum Technology
Steam jet ventilators are based on proven jet pump technology and often used to convey air, gases and vapors.

Steam jet ventilators are used to:
Steam jet ventilators convey air, gases and vapors against small pressure differences. They operate in a range between ∆p = 0 to 500 mbar. Above 500 mbar, steam jet compressors are used.
The achievable pressure difference between the suction pressure and discharge pressure is the compression of the steam jet ventilator.
Instead of steam, it is also possible to use compressed air or another gas as motive fluid for jet ventilators.
Apart from steam, air or gas, liquids may be used as the motive medium for jet ventilators.
As opposed to liquid jet ventilators, steam or gas jet ventilators have the advantage that larger pressure differentials can be managed.

Multi-stage steam jet vacuum pumps in graphite for corrosive applications.

Variable - Flow Ejectors are based on proven GEA jet pump technology and often used for heat recovery.

Steam jet compressors type bv1 are based on proven jet pump technology and often used used in evaporating, distillation, cooling, crystallization, deodorization, degassing and drying under vacuum.

Liquid jet liquid pumps are used for conveying and mixing liquids such as water, acids or lye in water and waste water treatment plants.
Since 2019, GEA has risen from underperformer to DAX member – one of Germany's top 40 listed companies – by fostering entrepreneurship and turning sustainability into a competitive advantage. It reached this milestone in its nearly 145-year history without tailwinds or shortcuts, in a world of compounding crises. This turnaround shows what's possible when purpose and performance align.
This year was a big one for GEA. Can you remember all the milestones and highlights?
The GEA Foundation launched this year with a promise: to make a tangible difference in people's lives. From scholarships in Germany to clean water in Tanzania, the foundation is already proving that when companies commit to giving back, lives change.
