Single piston double screen cavities screen change (oval)
Performance characteristics
Single piston double screen cavities screen changer is made of high temperature alloy steel, which has good performance in high temperature resistance and pressure withstand. It has two filter channels alternating work, and it is quick to change the net for easy production and maintenance. With high wear resistance, high precision filter design. Under the pressure of 30-50MPa and the temperature of 300-400℃, it will not affect its performance. Designed with suction exhaust structure, constantly change the net, no leakage, no interruption of production. It can ensure that the capacity is constant while changing the filter. It can be filtered by single net or double net simultaneously.
Scope of application
Single piston double screen cavities screen changer is suitable for the production of high pressure products, especially for blown film, cast film, double line drawing, wire drawing, granulation and other almost all thermoplastics.
