As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality PET Filter Cloth for Belt Filter that meets the rigorous demands of solid-liquid separation. Our polyester filter fabrics are engineered to provide consistent performance in dewatering, cake washing, and slurry filtration across various industries. With 1 year warranty and a Mill Test Report included for every shipment, we ensure your operations run smoothly with reliable filtration media.
Our PET filter cloth is woven from high-tenacity polyester monofilament or multifilament yarns, offering excellent dimensional stability, chemical resistance, and mechanical strength. The cloth is specifically designed for belt filter presses, horizontal belt filters, and vacuum belt filters, delivering superior cake release and low moisture content. Whether you need fine filtration for chemical processing or heavy-duty dewatering in mining, our product range covers micron ratings from 10 to 500 microns.
Key features of our PET filter cloth include:
- High tensile strength – withstands high belt tension without stretching or tearing, ensuring long service life.
- Excellent chemical resistance – resistant to acids, alkalis, and organic solvents, suitable for harsh environments.
- Uniform pore structure – provides consistent filtration efficiency and prevents blinding or clogging.
- Low cake moisture – optimized weave design reduces residual moisture, improving downstream processing.
- Easy cake discharge – smooth surface and anti-stick properties minimize cake adhesion.
- Heat resistance – operates continuously at temperatures up to 150°C, compatible with hot slurries.
- Customizable dimensions – available in widths up to 4 meters and any length, with or without selvedge edges.
- Mill Test Report included – provides detailed data on air permeability, thickness, weight, and tensile strength for quality assurance.

Frequently Asked Questions
-
Q: What is the typical lifespan of your PET filter cloth?
A: Lifespan depends on operating conditions such as abrasion, chemical exposure, and temperature. Under normal use, our cloth can last 6–12 months or longer. The Mill Test Report helps you track performance and plan replacements. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (A4 size) for evaluation. Custom samples can be made to match your required dimensions. Contact our sales team for details. -
Q: Do you provide custom sizes or edge finishing?
A: Absolutely. We can cut the cloth to any width and length, and provide options such as hemmed edges, welded seams, or adhesive tapes to fit your belt filter machine. Please provide your machine specifications. -
Q: What does the Mill Test Report include?
A: The report contains test results for air permeability, thickness, weight, tensile strength, and filtration micron rating. It is issued per batch and can be used for quality assurance and process optimization. -
Q: Is your PET filter cloth resistant to high temperatures?
A: Yes, it can withstand continuous operating temperatures up to 150°C, with short peaks up to 180°C. For higher temperature requirements, we recommend our PPS or PTFE series. -
Q: How do I clean the filter cloth to maintain performance?
A: Regular cleaning with low-pressure water or chemical wash (depending on the material being filtered) is recommended. Avoid using strong acids or alkalis that may degrade the polyester. We provide cleaning guidelines upon request. -
Q: What is your warranty policy?
A: We offer a 1-year warranty against manufacturing defects. If the cloth fails due to material or workmanship issues within the warranty period, we will replace it free of charge. Normal wear and tear, improper use, or chemical damage are not covered. -
Q: Do you offer technical support for selecting the right filter cloth?
A: Yes, our experienced engineers can help you choose the optimal weave, mesh size, and material based on your slurry characteristics, pressure, and desired cake moisture. We also provide free application testing for large orders.
