The dual bolt hydraulic screen changer allows for the changing of polymer filtration screens without stopping production by alternating bewtween to bolt positions. All gas in the polymer melt can be discharged through an advanced gas exhaust system design. This provides continuity and stability of the production process. Dual bolt hydraulic screen changers are used in compounding, masterbatch, recycling, sheet extrusion, profile extrusion, pipe production, pipe coating, and biaxial orientation.

Single bolt hydraulic screen changers use two working filter screen and are used in compounding, masterbatch, recycling, sheet extrusion, profile extrusion, pipe production, pipe coating, and biaxial orientation.
