Topas GmbH: Developed, Designed and Made in Germany

For over two decades the name Topas has stood for high-quality products and innovative efforts in the field of particle and aerosol technology.

Both domestic and customers abroad have taken profit from our ideas and experiences as a developer and manufacturer of equipment for the generation, measurement and dilution of airborne particles (aerosols) and complex test systems for filters, filter media and separators as well as for liquid filters. Our company philosophy allows a fast reaction to changes on the market and the realisation of particular customer wishes. Our own research and development as well as the close cooperation with universities and research institutions expand our know-how, which we pass on to our cus­­tomers through new solutions.

We translate market inputs into valuable findings to expand our product range and con­­stantly improve and optimise devices and facilities.
