The unique V-shaped wire profile provides a self-cleaning surface, reducing clogging and extending service life. The flange end connection allows easy installation and maintenance, while the 304 stainless steel construction guarantees excellent corrosion resistance and strength. Whether you need a single filter or a complete filtration system, our factory can customize slot openings, diameters, and end connections to meet your specific requirements.
Key Features & Technical Specifications
- Material: Premium 304 Stainless Steel – excellent corrosion resistance, suitable for potable water, food processing, and mild chemical environments.
- Slot Opening: 0.1 mm (100 microns) – fine filtration capability for particles down to 100 microns, ideal for sediment removal and polishing.
- Diameter: 250 mm – standard size for medium to large flow applications; other diameters available upon request.
- End Connection: Flange end – ANSI, DIN, or custom flanges for secure pipe connection, rated for high pressure.
- Working Pressure: 300 PSI (≈20.7 bar) – suitable for high-pressure pipelines and industrial processes.
- Wedge Wire Profile: V-shaped wire wound on support rods creates continuous slot openings, minimizing clogging and maximizing flow rate.
- Welding: Continuous resistance welding ensures strong joints and long-term structural integrity.
- Surface Finish: Standard pickled and passivated finish for enhanced corrosion resistance; optional electropolishing available.

Frequently Asked Questions (FAQ)
Q1: What is the difference between wedge wire filter and wire mesh filter?
A: Wedge wire filters use V-shaped wires wound on support rods, creating continuous slot openings that are more resistant to clogging and provide higher mechanical strength. Wire mesh filters are woven, which can be less durable under high pressure and prone to particle wedging.
Q2: Can the slot opening of 0.1mm filter particles smaller than 100 microns?
A: The slot opening defines the maximum particle size that can pass through. Particles smaller than 100 microns will pass, while larger particles are retained. For finer filtration, we offer slot openings down to 0.02mm (20 microns).
Q3: Is this filter suitable for food and beverage industries?
A: Yes, 304 stainless steel is food-grade and commonly used in food processing, breweries, and water treatment. Please confirm if any specific sanitary standards are required; we can provide electropolished finishes for improved cleanability.
Q4: What is the maximum temperature this filter can withstand?
A: 304 stainless steel wedge wire filters can withstand continuous operating temperatures up to 400°C (752°F) in air. For higher temperature applications, we recommend 310S or other heat-resistant alloys.
Q5: How do I clean the filter?
A: Backwashing with clean water or air is commonly used. The self-cleaning slot design reduces the need for chemical cleaning. For severe fouling, pressure washing or ultrasonic cleaning can be applied.
Q6: Can you provide a custom flange size?
A: Absolutely. We can manufacture flanges according to ANSI, DIN, JIS, or your custom drawings. Please provide the flange standard and dimensions when ordering.
Q7: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 10 pieces. Custom orders may have higher MOQ depending on complexity. We welcome small trial orders for testing.
Q8: How long is the delivery time?
A: For standard filters, delivery is 15–25 working days after order confirmation. Custom orders may require 25–40 working days. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports.
