Company History

ISI Industrieprodukte GmbH from Buchholz/Mendt, in the Westerwald area of Germany produces air filter devices for industrial air cleaning. The company was founded in 1973 and has developed into one of the leading filter device manufacturers in Europe. Customers worldwide have been successfully implementing our filter devices for over 40 years.

In 2012 ISI Vertriebs GmbH was set up as an independent sales company so that we can react more flexibly to the market and drive on our sales network further. The sales company sells in the name of ISI Industrieprodukte the ISI product range.

Amongst our customers are not only reputable automobile manufacturers but also major companies from the mechanical engineering sector as well as the metal working and plastic industries. For this clientele we equip turning, milling and grinding machines with extraction solutions.
