GVS Sub-vertical Mechanical Screens consist of a robust steel frame and a perforated plate filter varying according to the screening efficiency required.
GVS screens, which are equipped with brushes and wiper blades, are suitable for fine screening of sewage in both municipal and industrial plants, as well as, in particular, for process water of industrial processing plants.
Sub-vertical Mechanical Perforated Screens
