BETH Advanced Filtration

BETH® - »Air Pollution Control and Dedusting Technology« since 1887


Tradition and innovation – these have been the hallmarks of BETH’s history for more than a century. The company was founded in 1887 by W.F.L. Beth, an engineer from Lubeck, Germany, who invented the world’s first bag filter. The patent was issued as number #38396 by the “Kaiserliche Patentamt” on January 26, 1886.

Soon, the BETH bag filter found its way into other industrial branches, and in the course of the 20th century, BETH grew to be an international leader in the sector of industrial dedusting. At first, filtration was predominantly used for improving production processes, but by and by, it also became an important factor in operational safety and pollution control – long before “environmentalism” was an international buzzword.

Reducing noxious and hazardous dust emissions made industrial production not only more economically efficient and environmentally friendly, but also more humane. Before long, the term »BETH filter« became a synonym for dedusting itself.

In 1956, wet and dry electrostatic precipitators were added to the company’s range of products. In July 2004, BETH‘s commercial operations were taken over by WEIS INDUSTRIES® Holding GmbH. Today, BETH operates within this holding company as BETH® Filtration GmbH, an autonomous limited company, still situated in its traditional location in Lubeck, Germany.

In 2007, BETH converted its construction to 3D. In some instances, 3D technology is also used for project planning, enabling customers to gain a realistic image of their future plant even in the early offering and planning stages.

WEIS ENVIRONMENTAL offers tailor-made BETH engineering solutions. More than 100 years of experience and expertise in designing, constructing, and implementing dust removal systems make BETH the ideal partner for solving your dedusting problems.

Flexibility and modular design are the key factors that make our systems the perfect solution for all kinds of applications. BETH's highly versatile dedusters can be combined with additional components such as gas collection systems, ducts and pipes, coolers, fans, dust outlets, and various electronic devices.
BETH's state-of-the-art, high-quality products, combined with our in-depth expertise, make sure that we will find the perfect filter type for your particular application.

LTG AEROB® - »Setting standards since 1924.«

In 1924 the German engineer Dr.-Ing. Albert Klein (1880-1958), a.k.a. the »inventor of air engineering«, founds the first company for air technology on the European continent: »LTG Lufttechnische Gesellschaft mbH« in Stuttgart-Zuffenhausen, Germany.
