The Step Screen has the highest hydraulic capacity of any fine screen due to its larger open surface area when compared to any other Fine Screen technology. Step Screens are available with either 3mm or 2mm thick movable and 3mm or 2mm fixed lamellas. For the 2mm option, the open surface area for a clean screen is 75% (3mm thick lamellas = 60%).Web
