Filtration is not only required in vehicles.


Always and everywhere we have been concentrating on our core competence – filtration. For more than 55 years we have developed products, systems and concepts dealing with filtration and fluid management. And while we have already made a name for ourselves with many OEMs in the automotive industry, we also continue to be a renowned development partner for customers from many other industries.

Theory and practice.

Our applications are always based on comprehensive development and testing periods. Assisted by all common CAD software programs and extensive testing procedures, our developers work on solutions with optimal filtration efficiency and maximum tool life. By doing so, we profit from our interdisciplinary know-how, supplementing our development competence with high material and production competence. With our systems for FEM and CFD calculation we are able to meet any requirements right from the development phase.

We attribute special value to constantly enhancing our filter media. This applies to their quality as well as to their refinement, pleating and stamping. Depending on the respective application the task is to find the best material or material mix that corresponds best to a particular filtration requirement.

Patented and smart.

We are not satisfied with patented solutions. Our products have to be unique (and remain so) and that is why we take the safe route for our new developments and have them patented. It may be a new fiber technology for the filter medium, or a special stamping or pleating technique, or a particular housing design. To us and to our customers, the patents reflect the uniqueness of each development and they ensure an unvaryingly high product quality. And talking about uniqueness: The longest stamped filter cartridge in the world, which is up to 1,200 mm long, comes from Hengst.
