As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory offers high-quality wedge wire filters designed for demanding chemical processing environments. Our 0.4mm slot, 316L stainless steel wedge wire filter combines exceptional corrosion resistance with precise filtration, ensuring reliable performance in harsh chemical applications. With annual exports exceeding US$5 million and a global presence across North America, Europe, and Asia, we deliver products that meet rigorous industry standards.
The Wedge Wire Filter, 0.4mm Slot, 316L, Corrosion Resistant is engineered for solid-liquid separation in chemical processing, refining, and petrochemical industries. Its unique V-shaped wire profile provides a self-cleaning slot design, preventing clogging and maintaining consistent flow rates. The 316L stainless steel construction offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for acidic, alkaline, and high-temperature environments.
Key Features & Benefits:
- Precision Slot Size: 0.4mm (±0.02mm) ensures accurate particle retention while maximizing throughput.
- Corrosion Resistance: 316L stainless steel (low carbon) provides excellent performance in chloride-rich and acidic media.
- V-Shaped Wire Profile: Reduces binding and allows easy backwashing, extending service life.
- High Mechanical Strength: Continuous slot welding and robust support rods withstand high pressure and temperature fluctuations.
- Customizable Dimensions: Available in various lengths, diameters, and end connections (flanged, threaded, or welded) to fit existing systems.
- Easy Maintenance: Smooth surface and open slot design minimize fouling, simplifying cleaning and replacement.

Our manufacturing process employs advanced continuous slot welding technology, ensuring consistent slot width and structural integrity. Each filter undergoes rigorous quality control checks, including slot dimension verification, pressure testing, and material certification. The 0.4mm slot size is specifically chosen for chemical processing applications where fine particle removal is critical, such as catalyst recovery, polymer filtration, and acid clarification.
Compared to traditional mesh screens, the wedge wire design offers a larger open area (up to 60%) and lower pressure drop, resulting in higher flow rates and reduced energy consumption. The 316L grade further enhances longevity in corrosive environments, reducing replacement frequency and maintenance costs.
With over two decades of experience, Anping County Boli Hardware Wiremesh Products Factory has supplied wedge wire filters to clients worldwide. Our annual export value of US$5–10 million reflects our commitment to quality and customer satisfaction. We offer flexible shipping options from Tianjin, Qingdao, Shanghai, and Foshan ports, ensuring timely delivery to major markets including North America, Europe, Southeast Asia, and the Middle East.
We understand that chemical processing environments vary, so we provide customization services for slot size, dimensions, and end connections. Our technical team can assist with selecting the optimal filter design for your specific process conditions.

Frequently Asked Questions
1. What is the difference between wedge wire and wire mesh filters?
Wedge wire filters use a V-shaped profile wire wound around support rods, creating a continuous slot with tapered opening. This design resists clogging and allows easy backwashing, while wire mesh has a square weave that can trap particles more easily. Wedge wire is preferred for high-viscosity or abrasive media.
2. Can this filter be used for high-temperature applications?
Yes, 316L stainless steel can withstand temperatures up to 600°C in reducing atmospheres. However, for oxidizing environments, the maximum temperature is lower. Please consult our technical team for specific conditions.
3. Is the 0.4mm slot size suitable for removing fine particles?
Yes, the 0.4mm slot (400 microns) is effective for filtering particles down to approximately 400 microns. For finer filtration, we can supply smaller slot sizes (e.g., 0.1mm) upon request.
4. What end connections are available?
We offer flanged, threaded (NPT/BSP), and plain ends for welding or coupling. Custom connections such as quick-release clamps are also available on request.
5. How do I clean the wedge wire filter?
Backwashing with reverse flow is the most common method. The V-shaped slot allows trapped particles to be flushed out easily. For stubborn deposits, chemical cleaning or ultrasonic cleaning can be used without damaging the filter.
6. Can you provide material certificates?
Yes, we can provide material test certificates (MTC) for 316L stainless steel, including chemical composition and mechanical properties, upon request.
7. What is the typical lead time?
Standard sizes are usually shipped within 15–20 working days. Custom orders may require 25–30 days depending on complexity. We prioritize urgent orders based on stock availability.
8. Do you offer samples for testing?
Yes, we can provide samples of wedge wire filter segments (cut pieces) for evaluation. Please contact our sales team to arrange sample delivery.
