As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is committed to delivering high-quality filtration solutions. Our Stainless Steel Pleated Filter Cartridge is engineered for demanding water treatment applications, offering a perfect balance of precision and durability. With a 50 micron rating and high flow rate capability, this 20-inch cartridge provides efficient particle removal while maintaining low pressure drop, making it a reliable choice for industrial and commercial systems.
Key Features
- Premium Stainless Steel Construction: Made from 304 or 316L stainless steel, the cartridge resists corrosion, high temperatures, and chemical attack, ensuring long service life even in harsh environments.
- Advanced Pleated Design: The pleated configuration dramatically increases the filtration surface area (up to 5 times more than standard wound filters), resulting in higher dirt-holding capacity and extended intervals between cleaning or replacement.
- High Flow Rate: Optimized for liquid filtration, the cartridge supports flow rates of 20-30 GPM per 20-inch element (depending on fluid viscosity and system conditions), reducing the number of cartridges needed and saving space.
- 50 Micron Precision: The uniform pore size effectively removes suspended solids, sand, rust, and other particulates, making it suitable for pre-filtration, process water, and wastewater treatment.
- Reusable and Cleanable: Unlike disposable filters, this stainless steel cartridge can be backwashed, ultrasonically cleaned, or chemically regenerated, significantly lowering operating costs and waste.
- Versatile End Cap Options: Available with open end, 222 O-ring, or 226 O-ring configurations to fit standard housings and retrofit existing systems.

Applications & Benefits
- Water Treatment: Ideal for pre-filtration in reverse osmosis systems, municipal water plants, and industrial water reuse. The 50 micron rating protects downstream membranes and equipment from large particles.
- Chemical Processing: Resistant to acids, alkalis, and solvents, the cartridge can be used in aggressive chemical filtration where polymer or paper filters fail.
- Food & Beverage: Meets sanitary requirements for filtering beverages, cooking oils, and process water – easy to clean and sterilize.
- Oil & Gas: Suitable for produced water filtration, coolant systems, and hydraulic fluid cleaning.
- Cost Savings: By being reusable, the cartridge reduces consumable waste and replacement frequency. A single 20-inch element can last for years with proper cleaning, delivering excellent ROI.
- Eco-Friendly: Reduces landfill waste compared to disposable filter cartridges, aligning with sustainability goals.

Frequently Asked Questions
Q1: How do I clean this stainless steel pleated filter cartridge?
You can clean the cartridge by backwashing with clean water, using an ultrasonic bath, or soaking in a mild acid solution to dissolve mineral deposits. Avoid abrasive brushes to protect the pleated surface.
Q2: What is the expected service life of the cartridge?
Depending on operating conditions and cleaning frequency, the cartridge can last 1-3 years or more. Proper maintenance (e.g., periodic cleaning) extends its life significantly.
Q3: Can I use this cartridge for high-temperature applications?
Yes, when using 316L stainless steel, the cartridge can withstand temperatures up to 250°C (482°F). For 304 material, the limit is around 200°C (392°F). Please specify your temperature requirements.
Q4: Is the 50 micron rating absolute or nominal?
Our standard is nominal rating, but we can produce absolute-rated cartridges upon request. For absolute 50 micron, the filtration efficiency is >99% at that particle size.
Q5: Can I customize the end cap type or O-ring material?
Absolutely. We offer open end, 222, 226, DOE, and other end styles. O-ring materials include silicone, EPDM, Viton, and others. Please provide your housing specifications.
Q6: How does this compare to pleated polypropylene or melt-blown cartridges?
Stainless steel cartridges are more durable, reusable, and chemically resistant. They can be cleaned and reused, whereas polypropylene cartridges are typically single-use and have lower temperature limits.
Q7: What is the pressure drop across the cartridge at rated flow?
At 20 GPM with clean water, the initial pressure drop is approximately 0.5-1 psi. As the cartridge loads with particles, the pressure drop increases gradually, indicating when cleaning is needed.
Q8: Do you provide samples for testing?
Yes, we offer sample cartridges for evaluation. Please contact our sales team to discuss your testing requirements and shipping details.
With a strong production base in Hengshui, Hebei, and convenient shipping from Tianjin, Qingdao, or Shanghai, we ensure timely delivery worldwide. Our team is dedicated to providing technical support and after-sales service. Request a quote or sample today and experience the reliability of Boli Hardware filtration products.
