Double-piston big area screen changer
Double–piston big area screen changer is designed to consist of two pistons with each containing a filter screen, the two screens work at the same time, when a screen change is required, one of the pistons is moved out while the other remains in the operating position, and the melt flows continuously through the other piston, the pressure fluctuation is small, thereby meeting the requirement of high quality production.

Performance features/benefits
1.Large filtering area, High efficiency
2.Dual channels for filtration, no need to stop the working machine when changing the screen
3.Material leading and air exhausting design, product continuance
4.Small pressure fluctuation when changing screen, stable of the material flow.

Application
1.Cast film, plate, sheet, pipe, granulation, etc
2.Applicable to the production line of collosols, adhesive, coating and finishing materials and other blending agent products, used for filtration of mixture material.
