Product Description


1) Material leak-free mold
2) Hydraulic drive instead of manual operation
3) Affordable price



The new generation GM-DSP double  plate double working station screen changers ensures with their simple construction, highest quality and reliable processes for many years. The new sealing system allows the operation in extrusion lines with high pressures.
Customer's input and engineering know-how enabled deep studies to
adapt the design of internal flow channels and filtering chamber.

A remarkable reduction in maintenance costs have been possible thanks to the
introduction of these new manufacturing modifications. Due to the simple
and effective sealing system with interchangeable elements, also the most
difficult maintenance can be carried out directly at the customer's factory
reducing the machine down time.


In comparison with the double pillar double working  screen changer, the GT-DSP double plate type double working  screen changer allows a quicker screen change. This advantage is
based on the optimized volume of filtering chamber, which minimized the
duration of the venting procedure.
