Driving directions
From tube transport to fully automated quality control systems From tube transport to fully automated quality control systems
For more than 40 years, our success has been based on a very traditional means of transport: pneumatic post. Over the years we have continued the development of the pneumatic post to create fully automated high-tech systems. Material samples taken in the cement, steel, mineral and chemical industries go through the full sequence of processes - from sampling, through transport, unpacking, automatic sample preparation and analysis. Continuously perfecting sample analysis through the innovative systems always guarantees the highest quality.

2001: Sale of pfaff aqs to FLSmidth
Until 2001, pfaff aqs GmbH was an independent, privately owned company. The challenges of the global market, however, called for new structures. To ensure the future of the company and its workers, its owners decided to sell to the international FLSmidth group based in Denmark.
