In the “worlds” of electroplating and industrial washing, the filtering groups are indispensable components for the filtration of the liquid fluids present in certain “galvanic baths” and in the washing tanks. These components have excellent mechanical qualities and chemical resistance and are suitable for many types of liquids, even when the working conditions are “severe”.
