For the polyester spiral press filter fabric screen, we have a flexible selection of its fabric joints, including the endless joint, spiral joint, steel-clip joint and pin joint. Polyester Spiral Filter Screens are adding the filler wire into the spiral ring, so reducing the air permeability and there will be less material loss on the surface of the fabric.

The property of polyester spiral press filter fabric screen

As the polyester spiral fabric mesh is a herringbone design, sludge and mesh belt can be stripping quickly. Although it is easy to mud, a lot of mud is easy to clean. It can achieve the quick and easy connection. It is easy to install, saving time and improving production efficiency.

Applications of Polyester Spiral Filter Screen

Polyester Spiral Press Filter Screens intended for Belt Filter Press are mainly utilized in paper making, printing and dyeing, food, pharmaceutical, ceramics and solid-liquid separation industries like sludge dehydration. For the polyester spiral press-filter fabric, it is easy to peel the filter cake. In particular, adopting high-quality materials and advanced technology makes the joint with high strength, widely used in the city sewage treatment plant sludge dewatering.

The structure and advantage

To manufacture polyester spiral filter fabric screen, we use high-viscosity polyester, such as PET, PP, PA, monofilament materials by advanced equipment and process organization. 

It possesses the features of high tensile strength, acid and alkali resistance, high temperature resistance, good filter performance. Due to the stain-resistance and durablity, we can easily clean the polyester fabric. Moreover, our polyester spiral filter screen can maintain stable working.
