Press Filter Fabric (Filter Cloth)
Press filter fabrics and filter cloths for frame press filters, membrane press filters, drum, disc and leaf filters — oil, mining, lithium phosphate filtration and sludge dewatering.
Press filter fabrics for frame press filters, membrane press filters and drum, disc or leaf filters.
Vertical press filters — the cloth that has to walk
The vertical automatic press (Larox-type tower press) runs one continuous cloth zigzagging through the whole plate pack — a walking cloth up to ~55 m long, squeezed at up to 16 bar and washed every cycle. Dimensional stability, precise sealing edges and clean cake release are built into our weave for this duty.
Filters our cloths serve
- Frame (chamber) plate presses
- Membrane plate presses
- Drum, disc and leaf filters
- Vertical tower presses (Larox type)
Case — 1.5 m wide cloth in service
Woven wide so the cloth covers the full plate pack with minimal joints — more filtering area, fewer potential leak paths, faster fitting.

Frequently Asked Questions
How do I choose a filter press cloth?
Start from your filter type, particle size and chemistry: monofilament weaves release cakes easily and resist blinding; multifilament and staple weaves give finer retention; combination weaves balance both. We recommend per slurry.
What is the difference between monofilament and multifilament cloth?
Monofilament cloth is woven from single smooth yarns — best cake release and blinding resistance. Multifilament cloth uses twisted yarn bundles — finer filtration and clearer filtrate, at the cost of harder cake release.
Do you supply cloths for membrane filter presses?
Yes — including centrate drainage designs and seal edges for membrane plates.
Can the cloths be made seamless?
Barrel-neck and seamless cloths are available for full-plate designs on request.
What micron ratings are available?
From around 1 µm (needled) to 200 µm (open monofilament) — we quote a rating per weave after seeing your particle distribution.
Which material for lithium phosphate duty?
PP and PET cloths are typical; PVDF where temperature and chemistry demand. Send us pH and temperature for a recommendation.
