As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our premium Polyester Filter Press Cloth – a reliable solution for demanding solid-liquid separation processes. Each cloth is manufactured under strict quality control, backed by a 1-year warranty and accompanied by a Mill Test Report that confirms compliance with international ISO standards. This product is designed to deliver consistent filtration efficiency, extended service life, and cost savings for your operations.
Key Features & Technical Specifications
- Premium Polyester Material: Made from high-tenacity polyester fibers, offering excellent resistance to acids, alkalis, and abrasion. Suitable for continuous operation up to 150°C.
- Precision Weave Construction: Available in plain, twill, or satin weaves to optimize cake release, filtrate clarity, and flow rate. Each weave is tailored to your specific slurry characteristics.
- Customizable Dimensions: We can produce any size, shape, and cut (including pre-cut with holes, sleeves, or grommets) to fit your filter press model perfectly – no need for modifications.
- Exceptional Mechanical Strength: High tensile and burst strength ensure the cloth withstands repeated high-pressure cycles without deformation or tearing.
- Mill Test Report Included: Every shipment comes with a detailed report showing key performance data (weight, thickness, air permeability, tensile strength) – proof of consistent quality.
- 1-Year Warranty: We stand behind our product. Any manufacturing defect will be replaced free of charge within one year of purchase.

Benefits to Your Business
- Higher Filtration Efficiency: Optimized pore structure ensures faster liquid drainage and clearer filtrate, reducing cycle times and improving throughput.
- Longer Service Life: Polyester’s abrasion resistance and dimensional stability mean fewer replacements – up to 2-3 times longer than conventional polypropylene cloths in many applications.
- Easy Cake Discharge: Smooth surface finish minimizes cake adhesion, saving labor and reducing downtime between cycles.
- Consistent Performance: Each cloth is tested before shipment; the Mill Test Report gives you confidence in every batch.
- Global Compatibility: Our cloths are designed to fit all major filter press brands (including recessed plate, membrane, and overhead beam types).

Frequently Asked Questions
-
Q: How do I choose the right size for my filter press?
A: Please provide your plate dimensions, number of chambers, and any special cutouts (e.g., center hole, corner holes). We can manufacture to exact specifications – no need to modify your press. -
Q: What is the maximum temperature this cloth can withstand?
A: Continuous operation up to 150°C (302°F). For short-term peaks, up to 170°C may be acceptable, but we recommend testing under your actual conditions. -
Q: Is the cloth resistant to acids and alkalis?
A: Yes, polyester has good resistance to most acids (pH 2-12) and many organic solvents. However, strong oxidizing agents (e.g., concentrated nitric acid) may degrade the material – please consult our technical team for specific chemical compatibility. -
Q: What does the 1-year warranty cover?
A: The warranty covers manufacturing defects such as loose seams, holes, or dimensional inconsistencies. Normal wear and tear, damage from improper use, or chemical attack are not covered. We will replace defective cloths free of charge. -
Q: What is included in the Mill Test Report?
A: The report provides measured values for weight, thickness, air permeability, tensile strength (warp and weft), and elongation. Each batch is tested according to ISO standards, and a copy is sent with your shipment. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer free samples (A4 size or 30x30 cm) for evaluation. You only pay for shipping. Custom samples with your specific weave and finish can be provided at a nominal cost. -
Q: How long does production take?
A: For standard sizes and weaves, production takes 5-10 working days. Custom orders may require 10-15 working days. Expedited options are available upon request. -
Q: Do you have experience with international shipping?
A: Yes, we export to over 20 countries and territories. We can arrange FOB, CIF, or door-to-door delivery via sea, air, or express. Our logistics team ensures safe packaging and timely delivery.
