In Electroplating, it is necessary that certain corrosive chemicals in the electroplating bath are required to be continuously agitated or operated at high current densities. In such cases, solid particles remain suspended rather than settle at the bottom. These suspended particles cause roughness in plating.

In order to remove these suspended particles, continuous filtration of the bath is necessary which is done by Plate Filtration Unit. DiaFlow offers a range of Plate Filtration Systems engineered to provide absolute and economical removal of suspended solid or organic impurities from corrosive chemicals.

DiaFlow make Filter Units are provided with reusable PP Filter Cloth along with Filter Paper. Filter Units are also available with PP Filter Cartridges.
