Filter Cloth Knowledge Center
Reference material for engineers who have to specify, replace or troubleshoot a filter cloth — not a brochure library.
Sections that are live
Each section below has real content behind it. Sections still being written are listed separately — we do not publish empty shells.
Comparisons
Side-by-side engineering comparisons of slurries and machine routes that are routinely confused with each other.
Downloads
Datasheets and technical guides. Each document has its own landing page listing exactly what is inside.
FAQ
Questions we actually get asked during a quotation: selection logic, old-cloth photos, replacement versus OEM spare.
Video Index
Index of filtration videos organised by product opportunity and video ID. Nothing published yet.

These sections are being written. There is no page to link to until the content exists, so there is no link here.
- Selection guides — How an HVBF cloth is specified, polymer selection logic, how a tower-press cloth fails.
- Troubleshooting long-form — Deep diagnostics that feed the short problem pages.
- Testing methods — Air permeability, tensile strength, pore rating — method categories and how we report them.
The three documents most engineers open first
Phosphogypsum vs FGD gypsum
Two different by-products, two different plants, two different cloth decisions. The most common mix-up in gypsum dewatering.
HVBF cloth spec sheet
What a horizontal vacuum belt filter cloth datasheet has to state — pore rating, permeability, seam, width, chemistry.
Quotation FAQ
Why we ask for a photo of the old seam, what a replacement cloth is, and what we need before we can price anything.
Reading is not selection
Cloth selection is decided by your slurry and your machine, not by a web page. Send the machine brand and model, the belt dimensions and photos of the old cloth and its seam, and an engineer will work through it with you.
