As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we specialize in producing high-quality filtration solutions for industrial wastewater treatment. Our Stainless Steel Self-cleaning Filter Cartridge (50μm, 316L, 1.2MPa) is engineered to deliver consistent, low-maintenance filtration performance, reducing downtime and operational costs. With an annual export value of US$5–10 million and a global customer base across North America, Europe, Asia, and beyond, we ensure every cartridge meets rigorous quality standards.
This filter cartridge is designed for continuous operation in harsh environments, utilizing a robust 316L stainless steel construction that offers excellent corrosion resistance and durability. The self-cleaning mechanism, activated by backwash, automatically removes trapped solids, ensuring a steady flow rate and extended service life. Below are the key features and technical specifications:
Key Features & Benefits
- High Filtration Precision: 50μm absolute filtration removes fine particles, protecting downstream equipment and improving effluent quality.
- Self-Cleaning Efficiency: Automatic backwash cycle minimizes manual intervention, reducing labor and maintenance costs by up to 60%.
- Superior Material: 316L stainless steel withstands corrosive wastewater, chemicals, and high temperatures, with a max working pressure of 1.2MPa.
- Low Pressure Drop: Optimized internal structure ensures minimal flow resistance, saving energy and extending pump life.
- Easy Installation: Standard cartridge design fits most housing units; custom connection sizes are available.
- Long Service Life: Durable wedge wire or mesh construction (depending on model) offers up to 5 years of continuous use under normal conditions.
- Eco-Friendly: No disposable filter media required; reduces waste and supports sustainable water treatment.

Frequently Asked Questions
1. What is the working principle of this self-cleaning filter cartridge?
The cartridge uses a 316L stainless steel mesh or wedge wire element. During filtration, solids accumulate on the outer surface. When the pressure differential reaches a set point, a backwash cycle is triggered — either automatically or manually — flushing the debris out through a drain valve, restoring the filter without stopping the flow.
2. Can this cartridge be used for oily wastewater?
Yes, the 316L material is resistant to oil and many chemicals. However, for heavy oil or high-viscosity applications, we recommend consulting our technical team to select the appropriate mesh type and backwash frequency.
3. What is the maximum operating temperature?
The standard version operates up to 100°C. For higher temperature requirements (e.g., up to 300°C), we can customize the cartridge with different sealing materials and construction. Please contact us for details.
4. How often does the self-cleaning cycle need to run?
The frequency depends on the solid load and flow rate. In typical wastewater treatment, the backwash cycle may occur every 30 minutes to 2 hours. The system can be set to time-based or differential pressure-based activation.
5. Is this cartridge compatible with existing filter housings?
Our cartridge is designed with standard dimensions (e.g., 10", 20", 30", 40" lengths) and can fit most standard housings. We also offer custom sizes and connection types. Provide your housing specifications, and we will confirm compatibility.
6. What is the expected lifespan of the filter element?
With proper backwashing and regular maintenance, the 316L stainless steel filter element can last 3–5 years or longer, depending on water quality and operating conditions. It is reusable and does not require periodic replacement like disposable cartridges.
7. Do you offer samples for testing?
Yes, we provide sample orders for evaluation. Please contact our sales team to discuss sample availability and shipping costs. We can also supply a small-scale filter housing for testing if needed.
8. What certifications or quality standards do your products meet?
Our manufacturing process follows strict internal quality control procedures. While we do not claim specific third-party certifications unless explicitly provided, we can provide material test certificates and inspection reports upon request. Our products are designed to meet international water treatment industry standards.
With over 25 years of manufacturing experience, a dedicated R&D team, and a global logistics network, Anping County Boli Hardware Wiremesh Products Factory is your trusted partner for industrial filtration.
