BETH Filtration GmbH

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 Jan. 26, 1886.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. In 1956, wet and dry electrostatic precipitators were added to the company’s range of products.
