– Test stands for filter media testing and quality control –

It is important to test filter materials for certain properties in order to develop and optimize the production process of filters as well as to assure the quality of produced filters. Such properties, as for example, differential pressure and separation efficiency (that are related to particle size and loading capacity) are normally used to determine the filter parameters.

Through years of experience in the production of testing equipment, we were able to develop a wide range of solutions for a broad spectrum of testing systems. Customers all over the world rely on our professional experience, innovation and quality, that characterize our products.

With our equipment you can test diverse filter types according to different international standards (such as ISO, DIN, SAE, BS and JIS), because our machines are customized and certified in compliance with such norms.
