Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with annual export value exceeding US$5 million. Our String-Wound Cotton Filter Cartridge 30-Inch 10 Micron High Flow Rate is engineered to deliver consistent sediment removal for demanding industrial water applications. Combining deep bed filtration with high flow capacity, this cartridge ensures long service life and low pressure drop, making it a cost-effective solution for your pre-filtration needs.

The cotton string-wound structure creates a graded density that captures particles from 10 micron upwards, effectively removing sand, silt, rust, and other suspended solids. The 30-inch length provides extended surface area, allowing higher flow rates without compromising filtration efficiency. With a recommended change pressure of 2.0 bar, operators can easily schedule maintenance and avoid unexpected system downtime.

Key Features & Technical Specifications

Deep Bed Filtration: The random winding pattern creates multiple layers of filtration, trapping particles throughout the cartridge depth for higher dirt holding capacity.
High Flow Rate: 30-inch length and optimized fiber density allow flow rates up to 20 GPM (75 L/min) per cartridge under typical operating conditions (customizable based on system design).
Low Pressure Drop: The open structure reduces resistance, saving energy on pumping costs. Initial pressure drop is as low as 0.1 bar at nominal flow.
Wide Chemical Compatibility: Pure cotton fibers resist most aqueous solutions, alcohols, and mild acids/alkalis (pH range 4–10). For aggressive chemicals, optional polypropylene core is available.
Easy Installation: Standard 2.5-inch outer diameter fits most industry housings. Double O-ring sealed ends (with optional stainless steel core) ensure leak-free operation.
Long Service Life: Typical replacement interval is 3–6 months depending on feed water quality, with clear indicator at 2.0 bar differential pressure.

Customer Benefits

Reduced Maintenance Cost: The high dirt holding capacity means fewer cartridge changes, lowering overall operating costs.
Protection for Downstream Equipment: Effective removal of 10 micron particles extends the life of RO membranes, UV systems, and pumps.
Energy Savings: Low pressure drop across the cartridge reduces pump energy consumption by up to 15% compared to conventional pleated filters.
Reliable Supply: As a direct manufacturer with 20+ years of experience, we ensure consistent quality and on-time delivery.

Frequently Asked Questions

Q: What is the recommended replacement interval for this cartridge?
A: The replacement interval depends on feed water turbidity and flow rate. Typically, when the pressure differential reaches 2.0 bar, it is time to change. Under normal conditions, this can be every 3–6 months.
Q: Can this cartridge be used for drinking water?
A: Yes, the pure cotton string-wound material is food-grade safe. However, we recommend a final polishing filter (e.g., carbon block) for taste and odor removal if required.
Q: What is the maximum temperature this cartridge can withstand?
A: The cotton fiber can operate continuously at temperatures up to 60°C (140°F). For higher temperatures, consider a polypropylene core option which can handle up to 80°C.
Q: Is the cartridge compatible with all standard filter housings?
A: The standard 2.5-inch outer diameter and 30-inch length fit most industry housings with double open end (DOE) design. For customized housings, we can provide adapters or different end configurations.
Q: Does the cartridge contain any binders or adhesives?
A: No, our string-wound process uses mechanical winding without adhesives. The cotton fibers are held together by tension and winding pattern, ensuring no chemical leaching.
Q: Can I customize the micron rating or length?
A: Absolutely. We offer customized micron ratings from 1 to 100 micron, and lengths from 10 to 50 inches. Please contact our sales team with your requirements.
Q: What is the minimum order quantity (MOQ)?
A: For standard 30-inch cartridges, the MOQ is 100 pieces. For customized products, MOQ may vary – please inquire for details.
Q: How is the cartridge shipped?
A: We ship from Tianjin, Qingdao, or Shanghai ports. Cartridges are packed in cartons with individual plastic sleeves to prevent contamination. Sea and air freight options are available.
