Filter Presses
Plate type, feed arrangement, attachment, openings, and gasket or edge details determine the replacement fit. See Filter Press Cloth.
FILTER CLOTH
Industrial Filter Cloth for Solid-Liquid Filtration
Choose filter cloth by equipment, woven construction, material, and replacement or fabrication requirements. Start with the job the cloth must perform, not only the fiber name.

Choose the Right Filter Cloth
Start with the main question in your purchase or replacement project.
What Is Industrial Filter Cloth?
Industrial filter cloth is a porous textile used for solid-liquid separation. Liquid passes through while suspended solids form a cake, so the cloth affects filtrate clarity, drainage, cake release, cleaning, and cycle reliability. Fiber material, yarn, weave, finishing, permeability, attachment, and geometry must be considered together; a cloth suitable for one machine or slurry may not suit another.
Filter Cloth by Equipment Type
Different equipment types impose different fit and operating questions. Confirm the machine before choosing or quoting a cloth; final compatibility and supply scope depend on the drawing and process.
Centrifuges
Rotating equipment adds geometry, support, drainage, and mechanical loading questions. See Centrifuge Filter Cloth where relevant.
Belt and Continuous Equipment
Continuous dewatering and vacuum equipment use a separate belt product family. See Filter Belts rather than treating every belt as a press cloth.
Existing Machine Replacement
For an operating machine, the old cloth, drawing, plate details, and problem are useful starting evidence.
Materials and Weave / Construction
Choose material and construction together. Polypropylene and polyester can lead to different priorities for chemistry, temperature, mechanical loading, and cake behavior; woven construction adds yarn and weave choices that affect retention, drainage, blinding, and cake release.
Polypropylene
Often considered when chemical compatibility and an economical synthetic option matter. Confirm the actual chemistry and operating conditions.
Polyester / PET
Often evaluated when temperature tolerance or mechanical and dimensional demands matter more. Confirm liquid chemistry and operating conditions.
Woven construction
Yarn filament type and weave pattern change the balance between particle capture, cake release, flexibility, stability, and blinding.
Other materials
Nylon, PPS, aramid, PTFE, and other fibers may suit other filtration or dust-collection needs. Ask if the process requires another material.
How to Select Filter Cloth
Define equipment, separation result, material, and construction together; a fiber name is not a complete specification.
1. What equipment must it fit?
Identify filter type, plate or basket dimensions, feed, attachment, openings, seams, and gasket or edge requirements.
2. What is the liquid and slurry?
Provide liquid chemistry, solids, particle shape, concentration, temperature, and whether cake or filtrate is the priority.
3. What separation result matters?
Clarify filtrate clarity, drainage, cake dryness and release, cycle time, cleaning, and blinding.
4. What wear does the cloth see?
Consider pressure, flexing, abrasion, scraping, washing, backflushing, cycle frequency, and retained cake weight.
Custom Fabrication and Fit
A replacement may need an exact outline, feed opening, neck, seam, reinforcement, gasket, eyelet, tie, or other attachment detail. The construction must suit installation, support, cleaning, and machine loads. For a drawing-led or sample-led project, see Custom Fabricated Filter Cloth and provide the existing part or drawing.
Replacement Matching Process
- Identify the machine, filter type, plate or basket, and attachment method.
- Send the current cloth, drawing, measurements, photos, or manual pages.
- Record the slurry, liquid, solids, temperature, cleaning method, and operating problem.
- Compare material, yarn, weave, finishing, openings, seams, and edges.
- Confirm the final construction and quantity against the specification.
Industries and Applications
Filter cloth questions arise in mining and mineral processing, chemical processing, wastewater treatment, power and energy, cement, and metallurgy. The process context helps, but equipment drawings and slurry information still guide selection.
Mining & Mineral Processing
Review particle size, abrasion, cake handling, and dewatering equipment.
Chemical Processing
Review liquid chemistry, temperature, solids, and cleaning together.
Wastewater Treatment
Review sludge properties, filtrate clarity, cycle behavior, and fit.
Metallurgy
Review fine or abrasive solids and the required cake or filtrate result.
RFQ Information Required
For a useful quotation review, send as many of the following as are available:
- Equipment make, model, filter type, plate or basket size, and attachment.
- Existing cloth, drawing, dimensions, photos, quantity, and replacement history.
- Liquid, solids, particle characteristics, concentration, temperature, and chemistry.
- Target result: filtrate clarity, cake dryness, drainage, release, or cycle stability.
- Cleaning method, operating problem, and known blinding, wear, stretching, or leakage.
Filter Cloth FAQ
Is filter cloth selected by material alone?
No. Material, yarn, weave, finishing, equipment fit, attachment, slurry, and the desired separation result all interact.
Should I start with Filter Press Cloth or a material page?
Start with Filter Press Cloth when the machine is the main constraint. Start with PP or PET when material is the main question, then confirm fit.
Can a replacement cloth be made to fit an existing machine?
A drawing, sample, photos, and attachment details are the right starting evidence. Final fabrication details must match the specification.
What if I do not know the current cloth material?
Send old cloth, machine information, process conditions, and any label or purchase record. Verify the material rather than guessing from appearance.
