In the field of exhaust gas filtration there has long been a requirement for meshes that filter particles of different sizes while at the same time minimizing pressure loss. The volumetric mesh is the answer to this challenge. This is a further development of the TELA® mesh or 5-heddle weave developed by GKD back in the 1930s. The special weave of the volumetric mesh enables three-dimensional structures that perform this task. Moreover, the efficiency of the volumetric mesh is further enhanced by modern material combinations.
