Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a leading manufacturer specializing in industrial filtration solutions. With over two decades of expertise, we proudly present our Heavy Duty Cotton Wound Filter Element 50 Micron 40 Inch – a robust, high-performance filter designed for demanding water filtration plants. This element combines premium cotton wound technology with a standard-compliant design, ensuring reliable particle removal and extended service life. Trusted by clients across North America, South America, Europe, and Asia, our product delivers consistent efficiency and cost-effectiveness for large-scale water treatment systems.
Our filter element is engineered to meet the rigorous requirements of municipal and industrial water filtration plants. The 50 micron rating guarantees effective removal of suspended solids, sand, silt, and other particulates, while the 40-inch (1016 mm) length maximizes surface area for high dirt-holding capacity. Each element is wound from high-grade cotton fibers under controlled tension, creating a depth-filter matrix that traps contaminants throughout the entire thickness. This design reduces pressure drop and extends the interval between replacements, lowering operational costs for your facility.
Key Features & Technical Specifications
- Premium Cotton Wound Construction: Natural cotton fibers provide excellent chemical compatibility and high dirt-holding capacity, ideal for water with varying pH levels.
- 50 Micron Absolute Rating: Ensures removal of 99.9% of particles larger than 50 microns, meeting stringent filtration standards for plant influent and effluent.
- 40 Inch Standard Length: Compatible with most industry-standard filter housings (2.5-inch or 4.5-inch outer diameter options available).
- Heavy-Duty Design: Increased fiber density and reinforced core for high flow rates and pressure tolerance, suitable for continuous operation.
- Standard Compliant: Manufactured in accordance with international filtration norms, ensuring consistent quality and performance.
- Low Pressure Drop: Optimized winding pattern reduces resistance, saving energy on pumping systems.
- Easy to Replace: Double open end (DOE) design allows simple installation and removal without special tools.

Benefits for Your Water Filtration Plant: This filter element is specifically designed to handle the heavy particulate loads found in surface water, groundwater, and industrial process water. Its depth-filtration mechanism ensures consistent effluent quality, protecting downstream equipment like membranes, valves, and pumps. The 50 micron rating strikes an ideal balance between removal efficiency and flow capacity, making it suitable for pre-filtration or as a final polishing step in multi-stage systems. Additionally, the cotton material is biodegradable and environmentally friendly, aligning with sustainable plant operations.
Customization Options: We offer flexibility in end cap configurations (DOE, flat end, or with gaskets), core materials (stainless steel or polypropylene), and outer diameter sizes. For specialized applications, we can adjust the winding density and micron rating (from 1 to 100 micron) upon request. Our engineering team works closely with plant operators to ensure the filter element integrates seamlessly into existing housings and meets specific performance targets.

Frequently Asked Questions (FAQ)
Q1: What is the difference between nominal and absolute micron rating for this element?
A: Our 50 micron element is designed with a nominal rating that indicates the majority of particles of that size will be retained. For absolute rating (99.9% efficiency) we can customize the winding density. Please specify your requirement.
Q2: Can this filter element be used for wastewater or industrial process water?
A: Yes, the cotton wound construction is compatible with a wide range of aqueous fluids, including wastewater, cooling water, and process water with pH 4-10. For aggressive chemicals, polypropylene wound options are available.
Q3: What is the recommended replacement interval for this element?
A: Replacement frequency depends on influent turbidity and flow rate. Typically, under normal pre-filtration conditions, it lasts 3-6 months. We recommend monitoring differential pressure – replace when it reaches 2.0 bar (29 psi).
Q4: Does this element come with gaskets or O-rings?
A: By default, the element is supplied with double open ends. Optional gaskets (EPDM, Buna-N, or silicone) can be added for a sealed fit. Please specify your housing type.
Q5: Can I get a sample for testing before bulk order?
A: Yes, we offer sample units (1-5 pieces) at a nominal cost, with shipping via express. We also provide performance data sheets upon request.
Q6: Is the cotton material bleached? Does it affect water taste?
A: We offer both bleached and unbleached cotton. For drinking water applications, we recommend bleached (food-grade) cotton which is free of any taste or odor. Unbleached cotton is suitable for industrial use.
Q7: What is the outer diameter of your 40-inch element?
A: Standard outer diameter is 2.5 inches (63.5 mm). We also provide 4.5-inch (114 mm) for high-flow housings. Custom OD is available.
Q8: How do I ensure compatibility with my existing filter housing?
A: Please provide your housing's inner diameter, length, and end cap type. Our technical team will confirm fitment. Most standard housings with 40-inch double open end cartridges are compatible.
