Four channel design greatly increase filtering area, and meet the higher quality or quantity production demand.
Bigger filtering areas are applicable for different material or extrusion products.
It has better sealing characteristics with rigid sealing. The service life is longer.
It has material filling, air exhausting and impure material discharging function, which guarantees continuous production during screen changing.
It is applicable for high productivity, high efficiency, high quantity and continuous production of large extrusion plant.
It has reasonable structure design, easier operation and better working effect.
We can customize various sizes or standards based on the client’s requirement.
