The DIN/ISO 9001 certified quality management and in process controls of the major properties of the filter - elements ensures the consistent quality of all products. Optical checks are performed as well as laser- reference measuring of particle-retention properties, mechanical strength and porosity tests.

Continuous checks of our own manufacturing equipment take place as required by our quality management and make sure, that we meet the highest requirements in production.

We acknowledge the support of Brandenburg & Partner quality systems.
