Polyester Spiral Press-filter Fabrics is suitable for high-pressure press-filter washer, horizontal belt washer, pulp-liquor separator and netting belt coal-washer. It has been extensively used in all kinds of industries such as printing and dying, food, salt industry, pharmaceutical, environment protection, process hides, shoe-making, clothing, pottery and other conveyable belt etc.

Filtration fabrics for belt filter presses are characterized by high strength, resistance against abrasion and high dimensional stability. Fabric construction secures good water drainage and at the same time protects the sludge cake form going through the fabric. Individual fabric designs differ in speed of dewatering, size of apertures, surface smoothness for easy cake release, resistance against abrasion, etc.
