Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a trusted manufacturer specializing in precision filtration solutions. Our 316L Stainless Steel Johnson Wedge Filter with a precise 0.2mm gap is engineered for reliable solid-liquid separation in demanding industrial environments. Crafted from high-grade 316L stainless steel, this filter offers outstanding corrosion resistance and long service life, making it ideal for water treatment, chemical processing, food and beverage, and oil filtration. Backed by our 25+ years of manufacturing experience and annual export value exceeding US$5 million, each filter is produced with strict quality control to ensure consistent performance and customer satisfaction.
The Johnson wedge wire design features a continuous V-shaped wire wound around support rods, creating a durable slot opening that prevents clogging and enables efficient backwashing. The 0.2mm gap ensures precise particle retention while maintaining high flow rates. Below are key technical specifications:
| Property | Specification |
| Material | AISI 316L Stainless Steel |
| Gap Size | 0.2 mm (customizable from 0.1 mm to 6 mm) |
| Slot Profile | V-shaped (inward or outward flow) |
| Temperature Range | -20°C to +400°C (depending on application) |
| Standard Length | Up to 6 meters per section (custom lengths available) |
| Connection Type | Flange, Threaded, or Welded End (as per request) |
Key Features and Benefits:
- Precise Solid-Liquid Separation: The 0.2mm gap ensures high retention of fine particles while allowing maximum flow, reducing downtime and maintenance.
- High Strength and Durability: 316L stainless steel provides excellent resistance to pitting, crevice corrosion, and stress cracking, even in chloride-rich environments.
- Self-Cleaning Capability: The wedge wire design promotes efficient backwashing, extending service intervals and lowering operational costs.
- Customizable Dimensions: Available in various diameters (from 25 mm to 600 mm), lengths, and end connections to fit existing systems.
- Low Pressure Drop: The open area of the slot structure minimizes pressure loss, improving energy efficiency in filtration systems.
- Easy Installation and Maintenance: Lightweight yet robust construction simplifies handling and replacement, reducing labor time.
- Wide Application Range: Suitable for water treatment, desalination, oil & gas, chemical processing, mining, food and beverage, and pharmaceutical industries.

Frequently Asked Questions (FAQ):
-
What is the difference between 316 and 316L stainless steel for this filter?
316L has lower carbon content (max 0.03%) than 316, which reduces the risk of carbide precipitation during welding, providing better corrosion resistance in welded areas. Our filters are made from 316L to ensure long-term performance in harsh environments. -
Can the gap size be customized to other values?
Yes, we offer gap sizes from 0.1 mm to 6 mm. The 0.2 mm gap is a standard option, but we can adjust according to your particle size requirements. -
What is the maximum operating temperature for this filter?
Typically, 316L stainless steel can withstand up to 400°C in continuous service, but the actual limit depends on the media and pressure conditions. Please provide your operating parameters for a tailored recommendation. -
How do I clean the filter when it gets clogged?
The wedge wire design allows for effective backwashing or chemical cleaning. For most applications, simple backwashing with water or air is sufficient. We can provide cleaning guidelines based on your specific media. -
What connection types are available?
We offer flanged ends (ANSI, DIN, JIS standards), threaded (NPT, BSP), or plain ends for welding. Custom adapters can also be manufactured upon request. -
Do you provide samples for testing?
Yes, we can provide small samples (e.g., 200 mm length) for evaluation. Contact us with your requirements and we will arrange shipment. -
What is the typical lead time for this filter?
Standard sizes usually ship within 20-30 days after order confirmation. Customized orders may take 30-45 days depending on complexity. -
Can this filter be used for food processing applications?
Yes, 316L stainless steel is food-grade and meets FDA and EU regulations for food contact. We can provide surface finishes suitable for sanitary applications (e.g., electropolished).
