As a professional manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality Needle-Punched Filter Cloth Bags for Liquid Filtration. With over two decades of experience and an annual export value exceeding US$5 million, we provide reliable filtration solutions to clients across North America, Europe, Southeast Asia, and beyond. Our filter cloth bags are engineered to deliver consistent performance in demanding liquid filtration applications, backed by a 2-year warranty and a comprehensive Mill Test Report for every batch. This ensures you receive a product that meets strict quality standards and traceability requirements.

Product Features & Technical Specifications

High-efficiency needle-punched construction – The nonwoven felt structure provides a dense, uniform pore distribution that captures fine particles while maintaining high flow rates. It is ideal for liquids with low to medium viscosity.
Excellent chemical resistance – Available in polyester (for acidic/caustic environments) or polypropylene (for alkaline and organic solvents). Custom materials are available upon request.
Durable and long-lasting – The needle-punched felt is reinforced to resist abrasion, tearing, and repeated cleaning cycles. This reduces replacement frequency and lowers operational costs.
Customizable dimensions – We offer bags in various diameters (4 to 12 inches) and lengths (up to 36 inches or longer) to fit standard or custom bag filter housings.
Thermal stability – Operating temperature range: up to 150°C for polyester, 90°C for polypropylene. Higher temperature options are available on request.
Easy installation and sealing – Bags are equipped with a sewn-in collar, flange, or grommet for secure mounting. No special tools required.
Mill Test Report included – Each shipment is accompanied by a batch-specific test report detailing filtration efficiency, air permeability, tensile strength, and micron rating. This ensures full traceability and quality assurance.
2-year warranty – We stand behind the durability and performance of our filter bags. Any manufacturing defects within 2 years of purchase will be replaced free of charge.

Frequently Asked Questions (FAQ)

Q: What micron ratings are available for these filter cloth bags?
A: We offer standard ratings from 1 micron to 200 microns. Custom micron ratings are available upon request, and we can also produce bags with a gradient density structure.
Q: Can I use these bags for high-temperature liquids?
A: Yes. Polyester bags can handle up to 150°C, and polypropylene up to 90°C. For higher temperatures (e.g., 200°C+), we can supply bags made from PTFE or other specialty materials.
Q: How do I install the filter bag in my housing?
A: Our bags come with a sewn-in collar or flange that fits standard bag filter housing baskets. Simply slide the bag over the basket, ensure the collar seals tightly, and close the housing. No special tools required.
Q: Is the bag washable and reusable?
A: Yes, depending on the application. Needle-punched felt bags can be cleaned by backwashing, gentle pressure washing, or chemical cleaning. Repeated use reduces your replacement cost. However, for critical filtration, we recommend single-use to avoid cross-contamination.
Q: What does the 2-year warranty cover?
A: The warranty covers manufacturing defects such as seam separation, material degradation due to production flaws, or dimensional inaccuracies. It does not cover damage caused by improper installation, chemical incompatibility, or normal wear. We will replace defective bags free of charge.
Q: What is a Mill Test Report, and why is it important?
A: A Mill Test Report (MTR) is a quality document issued by the manufacturer that certifies the material properties and filtration performance of the batch. We provide MTRs for each shipment, including tensile strength, micron rating, air permeability, and material composition. This ensures traceability and helps you meet regulatory compliance.
Q: Can I customize the size and shape of the filter bag?
A: Absolutely. We offer full customization of bag diameter, length, collar style, and even the addition of drawstrings or handles. Just provide your housing dimensions, and we will produce a perfect fit.
Q: How do I place an order, and what is the lead time?
A: You can contact us via email or our website. For standard sizes, lead time is 5–10 working days. Custom orders may take 10–20 working days depending on complexity. We also offer expedited shipping upon request.
