The coarse filter range you can rely upon

Premium filter media, which are qualified for air filtration applications of all kind. Through the high regularity of the fibres, in what we have specialized our selves, you receive a filter media with an outstanding performance, a high dust holding capacity and a low pressure drop.

Our quality factors

Based on our long time research and experience in textile- and filtration technology as well as our frequent exchange of information with our partners, we could identify quality characteristics which make a difference and introduce those into all our products. Purchasing a filter media is always based on trust, therefore an excellent customer service and a constant high quality is our claim to fame.

Progressive Build-Up Progressive Build-Up

A gradual fibre build-up allows us to separate the dust particles by size within the filter media. This approach gives the air stream more space and lowers therefore the pressure drop drastically and maximizes the life span of the media. Cost and Energy savings are the benefits for you.

Inflammability and Flame Retardancy Inflammability

All our Filtermedia are fullfilling the high standards of the DIN EN 53 438 and reach the highest level F1/K1

Dust Safety Barrier Dust Safety Barrier

Through a special process we can solidify the clean air side or the filter mat what creates a safety barrier for the dust. This barrier protects you from dust break through when mechanical stress is performed in the filter mat.

Resistant Fibres Resistant Fibres

We only utilize high quality fibres for our air filters. This allows us to create stiff materials, what enables you to manufacture standing pockets who achieve the promised performance. Our media are 100% glass free and therefore suited for critical applications.

DIN EN 779 Sustainable filter tests

All our Filters are being tested by the official European Norm EN 779. All data provided to our media are therefore correct and reproducible.
