FAQ
Replace the forming fabric when any of these conditions are met:
- CFM increases >30% from baseline — indicates significant wear and fiber loss
- Thickness loss >25% — fabric is structurally degrading
- Tensile strength <75% of original — risk of catastrophic failure increases
- Sheet quality deterioration — wire marks, poor formation, or quality complaints
- Visible wear streaks at vacuum box positions or seam wear >50%
- Economic life reached — cost of quality issues and downtime exceeds remaining fabric value
Track both days and tons produced for optimal change scheduling.
