Therefore, the screen changer meets the customers’ requirement of higher productivity and better quality.

Performance characteristics:

1,Special sealed structure design(self-owned patent),excellent effect, no material.

2,Dual channels for filtration, no need to stop the working machine when changing the screen, no production interrupt, and more efficiency and less energy consumption without any defective product. Especially appropriate for the production of cast film, plate and sheet.

Application fields:

1,Used for the production of plate, sheet, cast film, pipe, granulation and so on.

2,Applicable to the production line of collosols, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture, filtering screen replacement available without machine halt.
