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 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 besides grinding mills, and in the course of the 20th century, the BETH machine factory grew into an international leader in the field 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.

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.
