As an expert for complex filtration processes, we set benchmarks with our application-optimized premium products and meet the challenges of these complex conditions with the inhouse development expertise of a large team of engineers. In agile product development processes and possibilities given by simultaneous engineering, we are able to forge ahead with great flexibility in every form of cooperation.
Every solution which is generated in this way is based on many years of experience and can be tailored to your specific application through the customized configuration of the components, materials and coatings. High-performance test facilities and a variety of test procedures enable us to provide a guarantee for all functionalities at all times.

For lasting success and the continuous development of innovations, we work together with various universities and institutes in order to ensure that technical expertise is always complemented by an outside view. The success of this approach is confirmed not only by satisfied customers but as well by many inhouse developments protected by numerous patents and utility models.
