Press Felt
Why Does My Press Felt Plug So Quickly?
July 5, 20263 min read
FAQ
Common causes of rapid press felt plugging:
Inadequate shower pressure (<20 bar) or clogged nozzles — Inspect weekly. One clogged nozzle = one accelerated fill stripe.
Chemical precipitation — Check pH levels, implement scheduled chemical cleaning.
Excessive carryover from forming section — Improve first-pass retention.
Felt design too dense for your stock — Specify a more open fiber layer structure.
Uhle box vacuum too low — Check vacuum level (target 30-50 kPa) and slot condition.
Prevention: Optimize shower pressure (20-35 bar), maintain nozzles, schedule chemical cleaning every 2-4 weeks.
