Benifits of this kind of double plate double working positions melt filter
The new generation GT-DSP double  plate double working positions  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.

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.

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.
