Tradition and innovation

... are a hallmark in the over one hundred year history of the BETH® brand.


On the basis of patent no. 38396, granted by the Imperial Patent Office on 26 January 1886, the inventor of the world's first bag filter, 
the Lübeck engineer Wilhelm Friedrich Ludwig Beth, founded his company in 1887.

Soon the BETH® bag filter found its way into other branches of industry in addition to being used in grinding plants. In the course of the 20th century, Maschinenfabrik BETH® became an international leader in the field of industrial dust removal.

While the original focus was on improvements to the production process, more and more filter systems were gradually added to increase operational safety and reduce the burden on the environment. This was already happening at a time when people were not yet aware of environmental protection. BETH® was far ahead of its time.

By reducing dust emissions, it was not only possible to work more economically and ecologically, but above all more humanely. In a short time, the term "BETH® filter" became synonymous with all types of dust removal equipment.

From 1956, the BETH® product range was expanded to include dry and wet electrostatic precipitators.

In 2013, the company and the worldwide known BETH® trademark were acquired by the shareholders of the R&R-TECHNIK company.
Through this acquisition, the products, service offerings and served market areas of both companies were merged.

The merger of R&R-TECHNIK and BETH® in 2015 to form R&R-BETH® created an innovative technology company. Today, R&R-BETH® has a unique variety of available products and technologies as a plant manufacturer across the globe.

Traditional values and experience as well as the profound training of young people are the basis of our sustainable growth. We seek active exchange with colleges, universities and research institutes as a bridge to science.
