Tradition and Innovation

encouraging good ideas and a readiness to get down to work

... these are 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 ECOPLANT Holding GmbH.

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

Since August 2013 BETH® Filter GmbH operates again as an independent company.
