Porous membrane with increased porosity and air permeability
has developed a mesh weave with rectangular pores, which offer increased porosity and air permeability. Given the same volumetric flow, the three-dimensional weave reduces the local pore velocity by up to 40%.
Porometric 150 μm offers a flow rate eight times greater than the mesh with the best sand reten- tion rate in the test. With the threedimensional high-performance mesh, GKD offers a filter medium which has high flow capacity and retention rate.
Its development was based on a comprehensive experimental study on erosion behaviour in pipelines. The Porometric mesh is a direct response to the finding that a
