For industry use we developed recently CombiFil®. CombiFil® is a blend of fine and coarse filaments, starting with fine at the filter surface to coarse at the exhaust side. This innovation technology allows the production of filter media with improved filter properties in the air media industrial cleanable filter cartridge segment.

The fine filaments will significantly increase particle retention and at the same time the coarse filaments will minimize the loss of pressure for low energy usage costs. The superior product properties of polyester spunbonds like high tensile strength, excellent stability and resulting optimum pleating properties are additional characteristic traits of CombiFil®.
