Pastic extruder exchange screen filter -two chanel screen changer
Double piston double working position screen changer
Performance characteristic:
1. The screen changer works simultaneously: when one net works, the other one replaced.
2. Exhaust system device can fully defuse the gas mixed in the materials and improve the product quality.
3. Double channels expand the filtration area to produce more high-quality production which meet the customers' need.
4. Apply to extrusion production in a wide range of materials and product.
5. Good sealing system ensures perfect sealing effect.
6. The function of filling material exhaust and pollution discharge guarantee the process of replacing screen continuously.
7. We design and manufacture production of various sizes according to the customers' requirement.
8. A well-designed structure makes operation more convenient .

How to work
The double piston Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Screen Changer consists of two pistons with each containing a filter cavity. When a screen change is required, one of the pistons is moved out of the housing while the other remains in the operating position. The dirty screen pack is removed and replaced with a new one. The piston is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other piston. This concept allows for continuous filtration with no interruption or loss of production.
