Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in high-quality filtration fabrics. Our PET Filter Cloth for Belt Filter is made from 100% virgin PET fibers, ensuring superior strength, chemical resistance, and consistent filtration performance. With a weight range of 300–700 gsm and thickness from 0.8–2.0 mm, this filter cloth is designed to meet the demanding requirements of belt filter applications in mining, chemical, food processing, and wastewater treatment industries. Each roll comes with a 1-year warranty and a mill test report to guarantee quality and traceability.
Our filter cloth offers excellent dimensional stability, high permeability, and long service life. The use of virgin PET avoids contamination and ensures consistent pore structure, making it ideal for fine particle retention and dewatering. We provide customized weaving patterns (plain, twill, satin) and edge treatments (selvedge, heat-cut) to suit different belt filter models. Below is a detailed overview of the product specifications and advantages.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between virgin PET and recycled PET filter cloth?
A: Virgin PET offers consistent fiber quality, higher strength, and no risk of contamination from unknown sources. It provides better filtration efficiency and longer life. Recycled PET may have variable properties and is not recommended for critical applications. -
Q: Can you provide samples for testing?
A: Yes, we can provide A4-size or small roll samples with customization. Please contact us with your requirements. Sample cost is negotiable, and we offer free samples for qualified inquiries. -
Q: How do I choose the correct weight and thickness for my belt filter?
A: It depends on the slurry characteristics, desired cake moisture, and belt tension. Higher weight/thickness offers more mechanical strength and better dewatering but may reduce permeability. We recommend consulting our technical team or testing with a sample. -
Q: What weave type is best for fine particle retention?
A: Plain weave provides tighter pore structure and is suitable for fine particles. Twill weave offers a balance of strength and permeability. Satin weave gives a smooth surface for cake release. We can produce all types. -
Q: Do you offer edge treatments like selvedge or heat cut?
A: Yes, we offer selvedge edges to prevent unraveling, heat-cut edges for clean finish, and stitched edges for extra strength. The choice depends on the application and belt filter design. -
Q: How long is the delivery time?
A: Standard rolls (100–200 m) can be shipped within 15–20 working days after order confirmation. Custom orders may take 25–30 days. We also offer expedited shipping for urgent orders. -
Q: Is the mill test report included with every shipment?
A: Yes, we provide a mill test report for each production batch, showing weight, thickness, tensile strength, and air permeability. Additional tests (e.g., pore size, burst strength) are available upon request. -
Q: What is the warranty coverage?
A: Our 1-year warranty covers manufacturing defects such as seam separation, uneven weave, or material flaws. Damage caused by improper installation, chemical attack, or mechanical abuse is not covered.
