Leaf Disc Filters
Leaf Disc Filters
- High pressure & temperature resistance up to 31.7MPa / 300℃.
- Large dirt-holding capacity and reliable permeability.
- Strong tenacity, impact resistance, and chemical corrosion resistance.
- Reusable and easy to clean, extending lifetime and minimizing downtime.
Advanced Polymer Film Filtration
Our filtration solutions for the polyester film process leverage advanced proprietary technologies to optimize product consistency, enhance quality, and minimize downtime.
During the process of film production, effective filtration is extremely important. All the waste particles, such as gels and physical materials, have to be removed. Because these waste particles can cause tears, create abnormalities on the surface of film. Lack of quality filtration in the continuous polyester film manufacturing process can have several negative consequences, such as frequent filter changes, decreased productivity, and lower product quality.
Our leaf disc filters are well-developed products after many years of improving using advanced professional welding equipment and processes. It is mainly used for polymer filtration in the production line of BOPA, BOPET, and BOPP, in order to remove polymer gel, coagulating agent, catalyst, and other solid impurities. Disc filters are widely applied in the industry of film, polyester polymer, spinning, packaging materials, engineering plastics, oil, chemical, and others.
