Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in industrial filtration solutions. Our PET Filter Cloth 120g/m² Lightweight Polyester is engineered for efficient belt filter operations in chemical filtration processes. Combining high tensile strength, excellent chemical resistance, and low weight, this cloth ensures optimal dewatering performance while reducing energy consumption. Whether you need reliable solid-liquid separation or fine particle retention, our product delivers consistent results in demanding environments.
This filter cloth is crafted from high-quality polyester (PET) fibers, offering a balanced combination of durability and flexibility. The lightweight 120g/m² design reduces drag on the belt system, extending equipment life. It is widely used in industries such as mining, chemical processing, food & beverage, and wastewater treatment. Below we detail its key features, specifications, and benefits.
Key Features & Benefits
- Lightweight Construction: At only 120 g/m², the cloth minimizes mechanical load on belt filters, leading to lower energy consumption and reduced wear on drive components.
- Excellent Chemical Resistance: Polyester resists acids, alkalis, and organic solvents commonly encountered in chemical filtration, ensuring long service life even in harsh environments.
- High Abrasion Resistance: The woven structure withstands continuous friction from cake discharge and belt movement, maintaining filtration efficiency over extended periods.
- Optimal Dewatering Performance: The carefully engineered pore size and air permeability allow rapid liquid drainage while retaining fine particles, achieving high cake solids content.
- Thermal Stability: Operates reliably up to 150°C continuous, suitable for hot slurry filtration without deformation or shrinkage.
- Customizable Dimensions: Available in various widths and lengths to fit different belt filter models, with options for edge sealing and seam types.
- Easy Cleaning: Smooth surface texture reduces cake adhesion, making it simple to clean between batches and maintain consistent performance.

Frequently Asked Questions
-
What is the maximum temperature this cloth can withstand?
Our PET filter cloth can operate continuously up to 150°C. For short-term peaks, it can tolerate up to 170°C, but we recommend staying within the continuous limit for optimal longevity. -
Can I order custom widths and lengths?
Yes, we offer customization. Widths from 1000 mm to 3000 mm and lengths up to 100 m per roll are available. Please provide your belt filter dimensions for a tailored solution. -
Is this cloth suitable for acidic filtrations?
Polyester has good resistance to most acids (pH 2–12). However, strong oxidizing acids or concentrated sulfuric acid may degrade the material. For extreme conditions, we can suggest alternative materials like polypropylene or nylon. -
How do I clean the filter cloth?
We recommend backwashing with water or a mild detergent solution. Avoid using harsh solvents unless verified. The smooth surface makes cleaning easier compared to heavier fabrics. -
What is the typical lifespan of this cloth?
Lifespan depends on operating conditions such as temperature, chemical exposure, and mechanical wear. In moderate chemical environments, our cloth can last 6–12 months with proper maintenance. We can provide a more accurate estimate based on your specific application. -
Does the cloth come with seams or is it seamless?
We offer both seamless (endless) and seamed versions. For belt filters, endless cloth is often preferred for better tracking. Please specify your requirement. -
Can I get a free sample before placing a bulk order?
Yes, we provide free samples (A4 size or small roll) for evaluation. You only need to cover shipping costs. Contact us with your details. -
What is the minimum order quantity (MOQ)?
Our MOQ is 100 square meters for standard products. For custom specifications, MOQ may vary. We are flexible to support both small trials and large-scale projects.
