Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over two decades of expertise in the wire mesh and filtration industry. Since 1998, we have been dedicated to producing high-quality filtration solutions for global markets, and our Polyester Filter Cloth for Belt Filter is a prime example of our commitment to precision and performance. This 800gsm, 1.0mm thickness filter cloth with 40% open area and 150 micron pore size is engineered to deliver efficient solid-liquid separation in belt filter applications, offering exceptional durability and consistent filtration results.
Our polyester filter cloth is woven from premium polyester filaments, ensuring high tensile strength, excellent abrasion resistance, and dimensional stability under demanding operating conditions. The balanced combination of weight (800gsm) and thickness (1.0mm) provides a robust medium that can withstand high pressure and continuous use, while the 40% open area and 150 micron precision allow for optimal flow rates and fine particle retention. Whether you are dewatering sludge, processing minerals, or filtering chemicals, this cloth is designed to maximize efficiency and reduce downtime.
Below, we present a detailed overview of the product specifications, key features, and the advantages it brings to your filtration process. We also address common questions to help you make an informed decision.

Key Features & Benefits
- High Mechanical Strength: The 800gsm weight provides exceptional tensile and burst strength, allowing the cloth to withstand high-pressure filtration cycles without tearing or deformation. This translates to longer service life and reduced replacement costs.
- Precise Filtration Efficiency: With a 150 micron pore size and 40% open area, this filter cloth offers an excellent balance between particle retention and flow rate. It effectively captures fine solids while maintaining high throughput, enhancing overall dewatering performance.
- Excellent Chemical Resistance: Polyester is inherently resistant to a wide range of acids, alkalis, and organic solvents, making this cloth suitable for harsh chemical environments. It also resists hydrolysis and microbial attack, ensuring stable performance in wet conditions.
- Smooth Surface & Easy Cake Release: The woven structure provides a smooth surface that facilitates easy filter cake release during belt filter operation. This reduces blinding and improves cleaning efficiency, minimizing downtime.
- Dimensional Stability: The 1.0mm thickness and tight weave construction maintain the cloth's shape and tension under repeated use, preventing sagging or misalignment on the belt filter. This ensures consistent filtration results over time.
- Customizable Options: We offer various weave patterns (plain, twill, satin), edge treatments (selvedge, heat-cut), and finishing processes (heat setting, calendering) to match specific application requirements. Width, length, and roll packaging can be tailored to your belt filter specifications.
Typical Applications
This polyester filter cloth is widely used in belt filter presses, vacuum belt filters, and horizontal belt filters across various industries:
- Mining & Mineral Processing: Dewatering of tailings, concentrates, and slurries (e.g., coal, iron ore, copper, gold).
- Chemical Industry: Filtration of pigments, catalysts, and fine chemical intermediates.
- Food & Beverage: Separation of starch, juice, and edible oils.
- Pharmaceuticals: Processing of active pharmaceutical ingredients (APIs) and fermentation broths.
- Wastewater Treatment: Sludge dewatering in municipal and industrial treatment plants.
- Environmental Protection: Filtration of flue gas desulfurization (FGD) gypsum and other industrial by-products.

Frequently Asked Questions (FAQ)
Q1: What is the maximum operating temperature for this polyester filter cloth?
A: Polyester filter cloth can typically withstand continuous operating temperatures up to 130°C (266°F) under dry conditions. For wet applications, the maximum temperature is usually around 90°C (194°F) to avoid hydrolysis. If you require higher temperature resistance, we can recommend other materials such as polypropylene or nylon.
Q2: Can this cloth be used in acidic or alkaline environments?
A: Yes, polyester has good resistance to dilute acids and alkalis, as well as many organic solvents. However, it is not recommended for strong bases (e.g., concentrated NaOH) or strong oxidizing agents. We recommend consulting our technical team for specific chemical compatibility.
Q3: How do I determine the correct width and length for my belt filter?
A: You can measure the existing filter cloth or provide the belt filter model specifications. We can produce custom widths up to 2.5 meters and any length required. Please provide the exact dimensions or a sample for accurate matching.
Q4: What is the typical lifespan of this filter cloth under normal operating conditions?
A: Lifespan depends on factors such as abrasiveness of the slurry, chemical exposure, pressure, and cleaning frequency. In many industrial applications, this 800gsm cloth can last 6–12 months or longer. We recommend periodic inspection and replacement based on filtration performance.
Q5: Do you offer samples for testing?
A: Yes, we can provide free samples (A4 size or small roll) for evaluation. The customer is responsible for shipping costs. Please contact us with your requirements and shipping address.
Q6: Is this filter cloth washable and reusable?
A: Yes, polyester filter cloth can be cleaned by backwashing, water jets, or chemical cleaning agents (compatible with polyester). Proper cleaning can extend the cloth's life and maintain filtration efficiency. Avoid using harsh scrubbing tools that may damage the weave.
Q7: What is the packaging for export orders?
A: Our standard export packaging includes polypropylene woven bags or cardboard boxes, with protective layers to prevent moisture and damage. Rolls are wrapped in plastic film and secured on pallets. Custom packaging (e.g., wooden crates) is available upon request.
Q8: How long does production and delivery usually take?
A: For standard specifications, production typically takes 7–15 working days. Custom orders may require 15–25 working days. Shipping time depends on the destination and method (sea, air, express). We have efficient logistics with multiple port options to ensure timely delivery.
