The dust removal of exhaust gases at high temperatures at an early stage is being demanded from an economical but also from an ecological point of view. Textile filter media made from synthetic fibres reach their limits in hot gas filtration because of their inadequate temperature resistance and their combustibility. Pyrotex® - KE85 offers the solution. The self-supporting elements are resistant up to 850°C, insensitive against flying sparks and non-combustible. A surface orientated filtration as well as high air permeability and high porosity guarantee extremely low emission rates.
