Backflush screen changer is our patent pending (international and Chinese)developed in 2009 .it is specially designed for recycling, compounding and large throughput extrusion process.

Due to the very effective screen cleaning with high pressure impulses, its rate of the screen-cleaning exceeds 80% ,  repeated usage up to 100-400 times (depending on the filtration fineness), minimizing the screen cost. Eliminate busy operation in the process of filter calcinations, ultrasonic cleaning, chemical immersion, and save the cost of various cleaning equipment.

100% availability of the production line while cleaning and replacing the screen, elimination of scraps. Low operation costs of production.
