For over two decades, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-performance filtration solutions. Our Needle-Punched Filter Cloth Bag is engineered to deliver superior dust capture and liquid filtration efficiency, backed by rigorous factory testing and a comprehensive 1-year warranty. Each bag is supplied with a Mill Test Report to ensure traceability and consistent quality, making it a reliable choice for industrial applications worldwide.
These filter bags are manufactured using advanced needle-punching technology, which creates a dense, three-dimensional fiber structure that effectively traps particles while maintaining low pressure drop. The fabric is produced from high-quality synthetic fibers, offering excellent mechanical strength, chemical resistance, and thermal stability. Whether you need a standard solution or a customized design, our factory can tailor the material, dimensions, and finish to meet your specific process requirements.
Key Features & Benefits
- High Filtration Efficiency: Needle-punched structure provides deep filtration, capturing particles from sub-micron to millimeter range. Ideal for dust collectors, baghouses, and liquid filter systems.
- Robust Construction: Fabric is mechanically interlocked without binders, ensuring high tensile strength, resistance to abrasion, and long service life even under harsh conditions.
- Factory Tested: Every batch undergoes rigorous quality control, including air permeability, burst strength, and particle retention tests. Mill Test Report included for full transparency.
- 1-Year Warranty: We stand behind our product. If any manufacturing defect is found within one year, we will replace or repair the filter bag at no extra cost.
- Customizable Options: Choose from various materials (polyester, polypropylene, nylon, etc.), weights (300–600 g/m²), thicknesses, and finishes. Custom sizes, cuffs, and grommets available upon request.
- Wide Application Range: Suitable for cement plants, steel mills, chemical processing, food & beverage, pharmaceutical, mining, and wastewater treatment.
