Stainless steel filter elements are made up of several layers of 316 mesh that are sintered together to form an integrated porous element. The middle mesh is of very fine gauge and determines the filtration efficiency of the elements. This layer is then overlaid with inner and outer layers of coarser mesh, to give support and protection. The elements are a typical surface filter and the contaminants are retained on the surface of the filtration layer, this makes cleaning and back flushing a simple process. These filter elements should be ultrasonically cleaned to give best results. Stainless steel filter elements are particularly useful in heavily contaminated applications and for use as pre-filters before disposable type final filters. Gaskets are required with stainless steel filter elements. The options are Viton, PTFE or high temperature annealed copper. stainless steel wire cloth elements are idea for hostile or severe environments and applications. That is why clean ability is so important. All of our wire cloth stainless steel filter elements are easily restored back into service by back flushing, ultrasonic or other non-abrasive cleaning techniques. When used in filtration applications involving hazardous fluids, the clean ability of our stainless filter elements can significantly reduce disposal costs.
