The bullet proof solution for your final filtration stage

We present you with our fine filter product a media series, which will never leave you in the lurch. From adhesive coatings to dust safety barriers, you will find all known quality factors in our fine filter products.

In the fine filtration is a reliable high class filter the alpha and omega, because failure of the material can result in damage and consequential costs of unquantifiable amount. For our high standard we are only using premium material for our fine filters and we are continuously improving the performance of our filters. All our fine filters are additionally strengthened on the clean-air-side what makes the material more robust and stiffer. Therefore we can guarantee a solid and reliable filtration over the whole life span.

Protect your investment and resources sustainable with premium filters. The result will assure your decision.


Our Quality Factors

Thourgh long term research and experiance in textile- and filtration technology, as well as our very frequent exchange of information with our partners, we have isolated clear quality factors, which have been integrated into all our filtration products. Purchasing filtration media is combined with a high amount of trust into the manufacturer. Therefore a faultless customer service and a constant high quality is in our manifesto.

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.
