Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted manufacturer since 1998. Our Polyester filter cloth for belt filter, multifilament woven, 0.8mm thick, 150°C heat tolerance, 30-60 L/m²/s air permeability is designed to deliver consistent filtration performance in demanding industrial environments. Made from premium polyester multifilament yarns, this cloth offers excellent dimensional stability, chemical resistance, and a smooth surface that minimizes cake blinding. With a thickness of 0.8mm and precise air permeability of 30-60 L/m²/s, it provides an optimal balance between filtration efficiency and flow rate for belt filter applications. Whether you are separating solids from liquids in mining, chemical processing, or wastewater treatment, our filter cloth ensures reliable operation and extended service life.
Key Features & Benefits:
- High Temperature Resistance: Withstands continuous operating temperatures up to 150°C, making it suitable for hot slurry filtration without deformation or loss of strength.
- Multifilament Woven Construction: Provides a smooth, low-friction surface that reduces particle adhesion and facilitates easy cake discharge, improving overall filtration efficiency.
- Precise Air Permeability (30-60 L/m²/s): Engineered to deliver consistent airflow and liquid drainage, ensuring optimal dewatering and minimizing energy consumption.
- 0.8mm Thickness: Offers a durable yet flexible structure that resists wear and tear, while maintaining good permeability for rapid filtration cycles.
- Chemical Resistance: Polyester material is resistant to acids, alkalis, and organic solvents commonly found in industrial processes, extending the cloth's lifespan.
- Customizable Dimensions: Available in various widths and lengths, with edge treatments (heat-cut or stitched) to fit your specific belt filter machine.
- Cost-Effective Performance: Compared to other high-temperature filter media, our polyester cloth offers an excellent balance of performance and affordability.

Why Choose Our Polyester Filter Cloth? Our multifilament woven design ensures a smooth surface that reduces blinding and facilitates easy cleaning, resulting in less downtime. The 0.8mm thickness provides the right balance of strength and flexibility, allowing the cloth to conform to belt filter contours while maintaining dimensional stability under tension. The air permeability range of 30-60 L/m²/s is carefully controlled during weaving to meet the needs of various dewatering applications, from fine mineral slurries to chemical precipitates. Heat tolerance up to 150°C ensures reliable performance in hot processes, such as gypsum dewatering or hot oil filtration. Additionally, the polyester material is resistant to hydrolysis and microbial attack, making it suitable for long-term use in harsh environments.

Frequently Asked Questions (FAQ):
A: The polyester filter cloth can withstand continuous operating temperatures up to 150°C (302°F). For intermittent exposure, it can tolerate slightly higher temperatures, but we recommend staying within the specified limit for optimal longevity.
A: Yes, we can adjust the weave density and yarn count to achieve other air permeability values, typically between 10 and 100 L/m²/s. Please contact us with your specific requirements.
A: Polyester has good resistance to dilute acids and alkalis at moderate temperatures. However, for highly concentrated or extreme pH conditions, we recommend testing or considering alternative materials like polypropylene or PVDF. Our technical team can provide guidance.
A: Standard widths are 1000mm, 1500mm, 2000mm, 2500mm, and 3000mm. Length per roll is typically 50m or 100m, but we can cut to any length you need. Custom widths up to 3000mm are possible.
A: Installation methods vary by machine design. Our cloth can be supplied with stitched loops, flat ends, or heat-cut edges. We recommend providing your machine's dimensions and clamping system details so we can prepare the cloth accordingly.
A: Lifespan depends on operating conditions such as temperature, chemical exposure, mechanical wear, and cleaning frequency. In typical belt filter applications for dewatering, this cloth can last from 6 months to 2 years. Proper maintenance (e.g., gentle washing, avoiding sharp objects) extends service life.
A: Yes, we provide free samples (A4 size or small swatches) for evaluation. You only need to cover shipping costs. Contact our sales team to request a sample for your specific application.
A: The MOQ for standard sizes is typically 50 square meters. For custom specifications, MOQ may vary. We welcome both small and large orders, and can discuss flexible terms for trial orders.
