Double piston screen changer with four screen cavities

Double piston screen changer with four screen cavities features, advantages, and applications:
The design is four channels and four filters. The four filters are working simultaneously without stopping material flowing or mass production. Thus the non-stop screen changing can be achieved.
The exhaust air system is able to fully discharge the air inside the material or perforated plate which is to be replaced. It can avoid air forming in the product during screen changing, thus improve the product quality.
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.
It is configured with safety protection cover design.
It is used for chemical fiber, blown film, flat film, cast film, pipe, plate, wire, fiber, granulating, recycling pelletizing, etc.
