1.Features and Uses

Spiral filtration fabrics are made of abrasive resistant PET. The main advantage of spiral fabrics is the strong spiral seam, which has the same tensile strength and lifetime as the fabric. Spiral fabric can achieve a higher lifetime than woven fabrics if the lifetime of woven fabrics is limited by premature clipper seam failure.

Benefits

• Long lifetime
• Abrasive resistant design
• No problems with seam
• High flow rate
• Smooth glued belt edges

Examples of applications:

• Dewatering of industrial and municipal sludge on belt filter presses
• Dewatering of pulp and paper sludge
• Dewatering of mining and abrasive sludge
• Dewatering of sludge on horizontal thickeners
• Forming fabric for wooden boar production
• Conveyor belts
