Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer of filtration solutions since 1998. Our 316L Stainless Steel Wound Filter Cartridge 20 Micron is engineered for demanding industrial liquid filtration applications, offering superior corrosion resistance, high mechanical strength, and consistent filtration performance. With over 20 years of manufacturing expertise and an annual export value exceeding US$5 million, we deliver products that meet the rigorous standards of global markets including North America, Europe, and Southeast Asia.
This filter cartridge is constructed from high-quality 316L stainless steel wire wound in a precise, graduated density pattern. It provides depth filtration – capturing particles throughout the media thickness – while maintaining a low pressure drop and high dirt-holding capacity. The 20 micron rating ensures effective removal of suspended solids, rust, sand, and other contaminants from industrial liquids such as water, chemicals, oils, and solvents.
Key Features & Technical Specifications
- Material: 316L stainless steel – excellent resistance to chloride corrosion, oxidation, and high temperatures.
- Filtration Grade: 20 micron nominal – suitable for pre-filtration, polishing, or as a final filter in many processes.
- Wound Construction: Continuous winding creates a robust, pleat-free structure that resists deformation under pressure.
- High Dirt-Holding Capacity: Graduated density design traps particles in the outer layers, extending service life.
- Low Pressure Drop: Open structure minimizes flow resistance, reducing energy consumption.
- Temperature Range: Operates effectively up to 450°C (842°F) – ideal for hot liquid filtration.
- Customizable Dimensions: Available in standard lengths of 10, 20, 30, and 40 inches; outer diameter 2.5" (63mm) with inner diameter 1.125" (28mm). Other sizes upon request.
- Easy Cleaning: Can be backwashed or chemically cleaned, offering reusable performance.
Typical Applications
- Industrial water treatment (cooling water, process water, wastewater)
- Chemical processing (acids, alkalis, solvents)
- Petrochemical & oil filtration
- Food & beverage (hot liquids, edible oils)
- Pharmaceutical & biotechnology
- Electronics manufacturing (ultra-pure water systems)

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316L stainless steel for filter cartridges?
A: 316L contains molybdenum, which provides better resistance to chloride corrosion and higher temperatures. It is recommended for marine, chemical, and hot liquid applications. -
Q: Can this cartridge be cleaned and reused?
A: Yes, the 316L stainless steel wound cartridge can be backwashed, ultrasonically cleaned, or chemically cleaned (e.g., with acid or alkaline solutions). Proper cleaning extends its life significantly. -
Q: What end cap configurations are available?
A: We offer standard DOE (double open end), 222/226 O-ring, or custom end caps. Please specify your housing requirements. -
Q: Is the 20 micron rating absolute or nominal?
A: It is a nominal rating, meaning the cartridge captures the majority of particles ≥20 micron. Actual efficiency depends on fluid conditions. -
Q: What is the maximum operating temperature?
A: The cartridge can withstand continuous temperatures up to 450°C (842°F) in non-oxidizing environments. For oxidizing conditions, lower limits may apply. -
Q: How do I determine the correct replacement frequency?
A: Replacement depends on differential pressure, flow rate, and contaminant load. We recommend monitoring pressure drop; replace when it reaches 2.0–2.5 bar. -
Q: Do you offer samples for testing?
A: Yes, we provide samples (free or paid based on quantity) for evaluation. Contact us to arrange a trial. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 7–15 days after confirmation. Custom orders may require 15–30 days depending on complexity.
