Advantages of double-column hydraulic screen changer: 1. There are two channels for the polymer medium to flow on the two pistons of the screen changer. The polymer medium is filtered through the filter screen to clean the medium and produce high-quality products. The high-wear, high-pressure and high-precision filter screen design improves the effective area of ​​filtration and the quality of filtration.

2. Large filter area, suitable for extrusion production of different materials and different process characteristics, with good sealing characteristics; advanced design concept and high-precision processing quality and the exhaust control system used in conjunction with this series of screen changers Filter + exhaust characteristics.

3. Standard configuration with specifications of 80~270mm, and processing of other special sizes; when the pressure is 25Mpa and the temperature is below 300°C, its performance will not be affected.
