Anping County Boli Hardware Wiremesh Products Factory, established in 1998, proudly presents our Standard Compliant PP Nylon Filter Bags designed specifically for high-performance solid-liquid separation in centrifuges. With over two decades of manufacturing experience and annual export values reaching US$5 million - US$10 million, we bring unmatched expertise to every filtration solution. Our filter bags combine the strength of polypropylene and nylon to deliver exceptional durability, chemical resistance, and long service life — all backed by free technical support to ensure optimal performance in your specific centrifuge applications.
These filter bags are engineered to meet industry standards, providing reliable filtration for a wide range of liquids including chemicals, oils, paints, food products, and wastewater. The seamless construction and reinforced stitching prevent bursting under high centrifugal forces, while our custom sizing options ensure a perfect fit for any centrifuge model. Whether you need micron-rated filtration for fine particles or heavy-duty bags for coarse solids, our product line offers flexibility and consistency.
Key Features and Technical Specifications
- Material Excellence: Made from 100% virgin polypropylene (PP) and nylon fibers, offering excellent tensile strength, abrasion resistance, and chemical stability. PP withstands acids, alkalis, and organic solvents, while nylon adds thermal stability up to 220°C.
- Filtration Precision: Available in micron ratings from 1 to 500 microns. Our precision-woven fabrics ensure consistent particle retention, minimizing bypass and achieving high clarity in filtrate.
- Customizable Sizes: Standard dimensions include 4x8, 4x10, 6x12, 8x16 inches, but we can produce any size according to your centrifuge basket dimensions. No minimum order quantity for custom sizes — ideal for R&D and small-scale production.
- Reinforced Seams: Double needle stitching with high-strength thread, plus optional heat-sealed edges for extra leak protection. The seams are tested to withstand pressures up to 5 bar.
- Various Ring Options: Choose from plastic S-rings, metal rings (stainless steel or galvanized), or drawstring closures. Each ring type is designed for secure mounting and easy removal.
- Long Service Life: The combination of PP and nylon fibers enhances resistance to wear, flex fatigue, and chemical attack. Typical lifespan ranges from 3 to 12 months depending on application conditions, reducing replacement frequency and operational costs.
- Free Technical Support: Our team of filtration engineers provides complimentary assistance in selecting the right bag material, micron rating, and size. We also offer troubleshooting for cake release, blinding, and pressure drop issues.

Frequently Asked Questions (FAQ)
-
What is the typical lifespan of these filter bags in a centrifuge?
Lifespan depends on factors like operating temperature, chemical exposure, and particle load. Typically, our PP Nylon bags last 3–12 months. With proper maintenance and cleaning, you can extend service life. We offer free technical support to help you maximize bag longevity. -
Can you provide custom sizes for non-standard centrifuge baskets?
Absolutely. We manufacture custom sizes based on your exact dimensions. Please provide the inner diameter, height, and ring type. There is no minimum order quantity for custom sizes, making it easy for trials and small batches. -
Are these bags suitable for food-grade applications?
Yes, our PP and nylon materials are FDA-compliant (optional certification). We can produce bags meeting food safety standards. Please specify your requirement when ordering. -
Do you offer samples before bulk purchase?
Yes, we provide free sample bags for testing (shipping cost may apply). This allows you to verify performance in your specific centrifuge and process conditions. -
What is the difference between PP and nylon filter bags?
PP bags offer excellent chemical resistance to acids and alkalis, while nylon bags provide higher temperature tolerance and better mechanical strength. For aggressive chemicals, PP is recommended; for high heat or abrasive solids, nylon is preferable. -
How do I select the correct micron rating?
We recommend matching the micron rating to the particle size you want to remove. For example, 1–10 micron for fine polishing, 50–100 micron for general clarification, and 200–500 micron for coarse solid separation. Our technical support team can guide you based on your slurry analysis. -
What ring options are available?
We offer plastic S-rings (standard for most centrifuges), metal rings (stainless steel or galvanized), and drawstring closures. The ring type depends on your centrifuge basket design. Provide a sample or photo, and we will recommend the best fit. -
Can these bags be cleaned and reused?
Yes, depending on the application. Bags with open-ended construction can be washed with appropriate solvents or water. However, for fine filtration or when blinding occurs, disposable use may be more economical. We can advise on cleaning methods for your specific product.
