Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, with annual export value exceeding US$5 million, serving global markets including North America, Europe, Southeast Asia, and Oceania. Our Sintered Stainless Steel Filter Element for Water Treatment, Backwashable, 50 Micron, 304SS is engineered to deliver exceptional solid-liquid separation for demanding industrial and municipal water systems. Combining advanced sintering technology with robust 304 stainless steel construction, this filter element offers superior corrosion resistance, mechanical strength, and long service life, making it the ideal choice for wastewater treatment, process water filtration, and pre-filtration for reverse osmosis systems.
Our backwashable design eliminates the need for frequent cartridge replacement, significantly reducing operating costs and downtime. The 50 micron filtration grade ensures precise removal of suspended solids, sand, scale, and other particulates, while maintaining high flow rates. Whether you need a standard configuration or a custom solution, our factory can tailor the element to your exact specifications – including diameter, length, end connections, and surface finish.
Key Features & Technical Specifications
- Material: 304 Stainless Steel – excellent resistance to rust, chemicals, and high temperatures.
- Filtration Precision: 50 micron (nominal) – suitable for coarse to medium filtration tasks.
- Sintered Structure: Multi-layer woven wire mesh fused under high temperature and pressure, forming a rigid, porous matrix with consistent pore size distribution.
- Backwashable: Can be cleaned in place (CIP) by reverse flow, compressed air, or ultrasonic methods – extends service life by 5–10 times compared to disposable cartridges.
- High Mechanical Strength: Withstands high differential pressure up to 1.0 MPa (145 psi) and temperature up to 400°C (752°F).
- Flow Capacity: Optimized design minimizes pressure drop while maximizing effective filtration area.
- Easy Installation: Available with various end caps (open, closed, with gasket, flange, or threaded connections) to fit standard housings or custom vessels.
- Surface Treatment: Options include pickling, passivation, or electropolishing for enhanced corrosion resistance and cleanability.
- Customizable: Diameter from 20mm to 300mm, length from 100mm to 2000mm, and any micron rating from 1 to 200 microns.

Advantages & Customer Benefits
- Cost Savings: Backwashable design reduces replacement frequency and disposal costs – up to 80% lower total cost of ownership compared to disposable filters.
- Reliable Performance: Sintered structure ensures uniform pore size, preventing channeling and bypass, resulting in consistent filtration quality.
- Durability: 304SS withstands aggressive chemicals, high temperatures, and mechanical stress, ideal for harsh water treatment environments.
- Low Maintenance: Simple backwash procedure (reverse flow, air scour, or ultrasonic) restores original flow capacity quickly.
- Versatility: Suitable for a wide range of applications – groundwater treatment, cooling water filtration, industrial process water, RO pre-treatment, and more.
- Eco-Friendly: Reusable filter element reduces plastic waste from disposable cartridges.
- Customization: We can match any existing housing or design a custom element per your engineering drawings.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between sintered and woven wire mesh filter elements?
A: Sintered elements are made by bonding multiple layers of wire mesh under heat and pressure, creating a rigid, porous structure with controlled pore size and higher strength. Woven mesh alone is flexible and may allow media migration. Sintered elements offer better filtration consistency and backwashability. -
Q: Can this filter element be used for oil or chemical filtration?
A: Yes, 304 stainless steel is resistant to many oils, solvents, and mild chemicals. However, for highly corrosive media (e.g., strong acids), we recommend 316L or other alloys. Please consult our sales team for specific compatibility. -
Q: How often should I backwash the element?
A: Backwash frequency depends on the solids load. Typically, when differential pressure reaches 0.5–0.7 bar (7–10 psi), or when flow declines noticeably. Our design allows for multiple backwash cycles without degradation. -
Q: What is the maximum flow rate for a 50 micron element?
A: Flow rate depends on element diameter, length, and fluid viscosity. As a reference, a standard 250mm long element (60mm OD) can handle 5–15 m³/h of clean water. Contact us with your specific parameters for a detailed calculation. -
Q: Do you offer custom sizes? What is the lead time?
A: Yes, we can customize diameter, length, end connections, and micron rating. Lead time for custom orders is typically 10–15 working days, depending on complexity. Stock sizes may ship within 3–5 days. -
Q: How do I clean the element if backwashing is not enough?
A: For stubborn fouling, you can use ultrasonic cleaning in a water bath, or soak in a mild acidic or alkaline solution (e.g., citric acid, sodium hydroxide) followed by rinsing. Avoid using abrasive tools that may damage the sintered surface. -
Q: Is this element compliant with FDA or food-grade standards?
A: 304 stainless steel is generally considered food-grade, but we recommend 316L for applications requiring strict FDA compliance. Our standard elements are not certified for direct food contact unless specifically requested. Please confirm your requirements with our team. -
Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects under normal operating conditions. Extended warranty is available upon request.
