Product Description

Double piston continuous screen changer for PET monofilament production line

The features of the PET monofilament production line.
1, the viscosity of the raw material is low degree
2, the production can not be interrupted.

So it requires strict of the screen changer.
1, leak-free mold, our screen changer adopts the special sealing system, guarrantee no material leak.
2, continuous type means no interrup the production when change the screen.

Semi-finished product in our workshop 



Benifits of this kind of screen changer

1, Double-piston screen changer works simultaneously. One net works. Another replaced; Without interrupting the flow of material and production. And eventually fulfills the exchange of screen without stopping the machine.
2, Exhaust system device can fully defuse the gas mixed in the materials, then improving product quality. And double channels expand the filtration area to meet more productive, more high-quality production need s from customers.
