Single piston screen changer for filtration systems and demanding extrusion process - DSC


The discontinuously operating single piston screen changer, equipped with a screen cavity, offers a robust and economic alternative for extrusion and compounding applications which permit a brief interruption in the melt flow when changing the screen. Thus, it is also ideal for batch applications. After a batch is complete, a screen change can be made during an application-related shut-down of the unit.
