As a leading manufacturer with over 25 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory proudly presents our 304 Stainless Steel Wedge Filter Johnson Filter with a precise 0.5mm slot, 100 micron filtration rating, 2-inch NPT connection, and a robust 150 PSI pressure rating. This wedge wire screen is engineered for demanding solid-liquid separation applications, offering exceptional strength, clog resistance, and long service life. Our factory in Hengshui, Hebei, China, exports globally to markets including North America, Europe, Southeast Asia, and the Middle East, with annual export values exceeding US$5 million.
The Johnson Filter design features continuous V-shaped wire wound around support rods, creating a wedge-shaped slot that allows superior backwashing and self-cleaning performance. The 304 stainless steel construction ensures excellent corrosion resistance in water, oil, gas, and chemical environments. With a 0.5mm slot (approximately 100 micron opening), it effectively filters particles down to 100 microns while maintaining high flow rates.
Key Features & Technical Specifications:
- Material: 304 Stainless Steel (AISI 304) – suitable for drinking water, food processing, and mild chemical applications.
- Slot Size: 0.5mm (500 microns) – provides precise filtration for medium to coarse particle removal.
- Micron Rating: 100 micron – effective for capturing particles of 100 microns and larger.
- Connection: 2-inch male NPT threaded end – easy installation with standard pipe fittings.
- Pressure Rating: 150 PSI (10.3 bar) – suitable for moderate pressure systems.
- Design: Wedge wire (Johnson screen) – continuous slot with V-shaped wire for reduced clogging and efficient backwashing.
- Customizable Length & Diameter: Available upon request to fit your specific vessel or housing.
- Temperature Range: Up to 400°F (204°C) – depending on application conditions.

Why Choose Our Wedge Filter? The V-shaped wire profile ensures that particles are trapped on the surface rather than inside the screen, allowing easy cleaning and extended service intervals. The 304 stainless steel provides excellent resistance to rust and corrosion, making it ideal for both potable water and industrial fluids. The 2-inch NPT connection simplifies installation into existing pipe systems or filter housings. With a 150 PSI rating, it handles typical municipal and industrial pressure requirements.
Benefits for Your Application:
- High Flow Capacity: Open area ratio up to 60% reduces pressure drop and energy costs.
- Backwash Efficiency: Smooth slot surface prevents particle bridging, ensuring thorough cleaning.
- Durability: Welded construction with strong support rods withstands mechanical stress and vibration.
- Customizable: Available in various lengths, diameters, and end connections (flanged, female NPT, etc.).
- Cost-Effective: Long service life reduces replacement frequency compared to mesh screens.

Frequently Asked Questions
1. What is the difference between wedge wire filter and wire mesh filter?
Wedge wire filters use V-shaped wires wound around supports, creating a continuous slot that is stronger and less prone to clogging than woven mesh. They are ideal for backwashing and high-pressure applications.
2. Is the 0.5mm slot suitable for 100 micron filtration?
Yes, the 0.5mm slot width corresponds to approximately 500 microns opening, but the effective filtration rating can be 100 micron depending on particle shape and application. Please consult our technical team for precise sizing.
3. Can I use this filter for drinking water?
Yes, 304 stainless steel is food-grade and safe for potable water. However, we recommend confirming with local regulations and ensuring proper end connections.
4. What is the maximum temperature this filter can withstand?
304 stainless steel can handle up to 400°F (204°C) in continuous service, but the actual limit depends on the gasket material and pressure. For high-temperature applications, please specify.
5. How do I choose the right length and diameter for my housing?
Please provide your vessel dimensions, flow rate, and desired slot size. We can manufacture custom lengths and diameters to fit your existing system.
6. Do you offer other end connections besides NPT?
Yes, we can provide flanged ends, female NPT, BSP threads, or custom connections. Please inquire with your requirements.
7. How is the filter delivered?
We pack each filter individually in cartons or wooden crates to prevent damage. For bulk orders, we offer custom packaging.
8. Can I request a sample before placing a large order?
Absolutely. We offer sample orders for evaluation. Please contact us with your shipping details and we will provide a quote.
