Filter Elements made from Woven Wire Cloth Laminated PanelsCharacteristics and Applications: Porostar® is a woven wire cloth laminate. Its individual woven wire cloth layers are closely bonded together by diffusion. The final diffusion results from a second thermal treatment after the first sintering process. The DUO-SINTER-TECHNIQUE employed in the manufacture of Porostar® leads to the diffusion of all wires in contact with one another. The geometrical structure of the individual woven layers is preserved. A stable porous filter plate is thus created, with predetermined characteristics in terms of pore-size, pore distribution, porosity and permeability. Porostar® can be formed and welded and is corrosion resistant. Porostar® for filtration and fluidizing purposes in many industries: chemical, petrochemical, pharmaceutical, plastic, food, automobile, mechanical engineering and many others It is a filter medium making possible a migration-free filtration in the range from < 1 micron to 200 microns. Even at maximum pressure, Porostar® cannot release any small parts of the filter medium.
Porostar® is manufactured as STANDARD-type and as special types LIGHT, HIFLO and COMBI. Specifications up to 10 mm thick have been produced.
Porostar®-Standard is put in filter sheets and cylinders. It is designed with five or six layers and specially suitable for unbalanced loads.
Porostar®-Light is suitable for the manufacturing of pleated filter cylinders and discs with very small diameters, e.g. 2.5 mm, and is composed of three woven wire cloth layers.
Porostar®-HIFLO Because of its important flow capacity Porostar® HIFLO is specially suitable for sieving and filtering methods using minimized pressures. Each woven wire cloth layer has square meshes.
Porostar®-Combi is suitable for high pressures even in reverse direction flow. Woven wire cloth layers and a perforated metal plate are bonded by sintering. Porostar®-Combi is available in Standard-type and in special types light or HIFLO as well. The number of layers and the thickness of the perforated metal plate are variable.
