Double-piston continuous screen changer realizes a non-stopping screen changing operation by altering two pistons with double filtering areas. During production, the polymer melt is divided into two flow channels inside the screen changer housing, then conveyed through the two filters equipped with the appropriate filter medium. This filter medium consists of screen packs supported by breaker plates.

 

It can match with extruders of different design . It is applicable to process with most polymers at high output.

Double-channel nonstop screen changer work alternatively, which can change the screen with minimum melt pressure fluctuating and production interrupting.

Two stages air vent for the hydraulic system to eliminate bubbling in polymer flow.

Superior sealing system completely eliminates polymer leakage.

External safety cover gives better appearance and safe protection.

It is equipped with circular, elongated or U- shaped screens, for enlarged  filtration area.

It can be used for synthetic  fiber, blown film, flat film, casting film, pipe, sheet, wire manufacturing, cutting line, Recycling and so on.
