As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory introduces our premium 304 Stainless Steel Wedge Wire Filter Element with an ultra-fine 0.1mm slot size, specifically engineered for high-efficiency water filtration. This product combines decades of wire mesh expertise with advanced wedge wire technology, delivering a robust, corrosion-resistant, and long-lasting filtration solution that meets the demanding needs of industrial and municipal water treatment systems. Our factory's annual export value of US$5–10 million to global markets including North America, Europe, and Asia underscores the trust and reliability that clients place in our products.
The 304 stainless steel construction ensures excellent resistance to rust, chemicals, and high temperatures, making it ideal for both potable water and wastewater applications. The unique wedge wire profile provides a v-shaped slot that prevents clogging and allows for easy backwashing, significantly reducing maintenance downtime. Each filter element is fabricated with precision to achieve a consistent 0.1mm slot opening, ensuring accurate solid-liquid separation down to 100 microns.
Our filter elements are fully customizable in terms of length, diameter, connection type (flange, thread, or plain end), and end cap design, allowing seamless integration into existing filtration systems. Whether you need a single element for a pilot project or bulk supply for a large-scale water treatment plant, we can accommodate your requirements with short lead times.
Key Features & Technical Specifications
- Material: 304 stainless steel – high corrosion resistance, suitable for freshwater, seawater, and chemical solutions.
- Slot Size: 0.1mm (100 microns) – precise and uniform slot width for reliable filtration.
- Wedge Wire Profile: V-shaped wires with continuous slot – self-cleaning design reduces blinding.
- Structural Strength: Heavy-duty support rods and continuous welding ensure high pressure resistance (up to 10 bar standard).
- Customizable Dimensions: Outer diameter from 50mm to 600mm, length from 100mm to 3000mm, or as per drawing.
- Connection Options: Flanged, threaded, or plain ends – available with gaskets for leak-proof installation.
- Surface Finish: Smooth, polished, or pickled surface – easy to clean and maintain.
- Backwash Capability: Low pressure drop during backwashing, extending service life.

Advantages Over Traditional Filter Media
- Non-Clogging Design: The wedge wire slot continually widens from the inner to outer surface, allowing particles to pass through or be easily dislodged during backwashing.
- High Open Area: Up to 60% open area ensures low pressure drop and high flow rates, increasing system efficiency.
- Uniform Filtration: Automated slot winding process guarantees slot width variation within ±0.02mm, providing consistent filtrate quality.
- Long Service Life: 304 stainless steel resists corrosion and abrasion; typical lifespan exceeds 5 years in normal water conditions.
- Easy Maintenance: Smooth surface and self-cleaning geometry reduce manual cleaning frequency; backwash with water or air saves time and labor.
- Environmentally Friendly: Reusable and recyclable, eliminating disposable filter media waste.
Applications
This filter element is widely used in:
- Municipal water treatment (pre-filtration, clarification)
- Industrial process water filtration (cooling towers, boiler feed)
- Wastewater treatment (primary and tertiary filtration)
- Seawater desalination pre-treatment
- Food and beverage industry (wash water, rinse water)
- Chemical and petrochemical applications

Frequently Asked Questions
Q1: What is the difference between wedge wire and woven wire mesh filter elements?
A: Wedge wire (Vee-wire) elements are made by wrapping continuous V-shaped wire around support rods, creating a continuous slot that is non-clogging and self-cleaning. Woven wire mesh uses intersecting wires, which can be more prone to blinding. Wedge wire offers higher strength and longer life for heavy-duty water filtration.
Q2: Can the 0.1mm slot size be customized to other sizes?
A: Yes, we offer slot sizes from 0.05mm to 3.0mm. The 0.1mm slot is standard for fine filtration, but we can adjust to meet your specific particle removal requirements.
Q3: How do I determine the correct length and diameter for my filter system?
A: We recommend measuring the housing chamber dimensions or providing your existing filter specifications. Our engineers can also design based on flow rate, pressure drop, and desired filtration area. Custom sizes are available upon request.
Q4: What is the maximum operating temperature for 304 stainless steel wedge wire?
A: 304 stainless steel can withstand continuous operating temperatures up to 425°C (797°F) in air, but for water filtration, typical temperature range is 0–100°C. For higher temperatures, 316L or other alloys are recommended.
Q5: Do you offer flanged connections? What standards are available?
A: Yes, we provide flanged connections per ANSI, DIN, JIS, or other standards. Threaded (NPT/BSP) and plain ends are also options. We can weld, thread, or machine end caps as needed.
Q6: How do I clean and maintain the filter element?
A: The wedge wire design allows easy backwashing with water or air at low pressure. For heavy fouling, chemical cleaning with mild detergents or acids (citric acid) is effective. The smooth surface resists sticking, and the element is fully reusable.
Q7: Is the product tested before shipment?
A: Yes, each filter element undergoes visual inspection, slot size measurement using feeler gauges or optical tools, and a pressure test to ensure leak-free performance. We provide a quality inspection report with each shipment.
Q8: What is the typical lead time and delivery terms?
A: For standard sizes, lead time is 10–15 working days. Custom orders may take 20–25 working days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports, with flexible terms (FOB, CIF, etc.).
