During the last four decades, Arnold Jäger and his sons have taken out more than 30 patents on aeration technology in Europe and the USA.

Dr.-Ing. Andreas Jäger, oldest son of Arnold Jäger, joined the company in 1995. Under his leadership the development team of the Jäger Group perpetually improved the aeration technology. In order to meet the growing importance in the field of aeration systems, all German Jäger activities concerning waste water treatment have been transferred to Jäger Umwelt-Technik GmbH in 2007.

At the same time, Jäger’s American  business has been sold to Claudius Jäger and is today branded as Gummi-Jaeger Aeration. The product portfolio of Jäger Umwelt-Technik GmbH (Hannover, Germany) and Gummi-Jaeger Aeration Inc. (Longmont, USA) is based on their mutual heritage up to 2007. Since then both companies have individually developed specific products for their markets / customers.

Therefore, nowadays the product lines may look similar, but bear significant technical differences.

In 2005 Jäger complemented its diffuser business with the Cleartec Biotextiles technology. Introducing the innovativ fixed film process into the global marketplace Jäger Umwelt-Technik GmbH has developed from a component supplier into a true process company.

Jäger-Umwelt-Technik GmbH is formulating and processing all rubber compounds in house in its own mixing facility. We produce the best suited membrane materials for municipal and industrial applications based on our 40 years experience.

All Jäger Umwelt-Technik GmbH products are „Made in Germany” and are based on constant innovation by German engineering.
