Anping County Boli Hardware Wiremesh Products Factory proudly presents our premium 304 Stainless Steel Wedge Wire Johnson Filter with a precise 0.5mm slot width and 1000mm length, engineered specifically for high-efficiency water filtration. As a dedicated manufacturer since 1998, we specialize in producing robust wedge wire screens that offer superior filtration performance, excellent mechanical strength, and long service life in demanding environments. Our Johnson filter is designed to handle a wide range of water treatment applications, from municipal water supply to industrial process water, ensuring reliable solid-liquid separation with minimal clogging. The V-shaped wire profile ensures self-cleaning characteristics, reducing maintenance frequency and operational costs.
This product is manufactured using 304 stainless steel, providing excellent corrosion resistance and durability suitable for both fresh and saline water conditions. The 0.5mm slot width is ideal for fine filtration, capturing particles down to 0.5mm while maintaining high flow rates. The 1000mm length offers flexibility in installation, and custom sizes are available upon request. Below we outline the key features, technical specifications, and benefits to help you understand why our wedge wire filter is the optimal choice for your water filtration needs.
Key Features & Benefits
- Precision Slot Width of 0.5mm: Ensures accurate particle retention, ideal for water clarification, desanding, and pre-filtration.
- 304 Stainless Steel Construction: Resists rust, chemicals, and biofouling, extending service life in harsh environments.
- V-Shaped Wedge Wire Profile: Promotes self-cleaning action – contaminants slide off the wire surface, reducing blinding.
- High Open Area Ratio: Maximizes flow capacity while maintaining structural integrity.
- Strong Welded Joints: Continuous resistance welding ensures consistent slot dimensions and prevents wire loosening.
- Customizable Lengths and Connections: Available with threaded ends, flanges, or plain ends to suit your system.
- 1000mm Standard Length: Convenient for modular installations, with custom lengths available upon request.
- Low Maintenance: Self-cleaning design reduces the need for frequent backwashing or manual cleaning.

Frequently Asked Questions (FAQ)
Q1: What is the difference between wedge wire screen and Johnson screen?
There is no difference – “Johnson screen” is a common term for a wedge wire screen that uses continuous V-shaped wire wrapped around support rods. Our product is exactly that: a durable, self-cleaning filter screen.
Q2: Can I use this filter for seawater or brackish water?
304 stainless steel offers good corrosion resistance in freshwater and mildly saline environments. For highly saline or corrosive water, we recommend 316L stainless steel or other alloys – please contact us for recommendations.
Q3: What is the maximum pressure the filter can withstand?
Pressure rating depends on the diameter, wall thickness, and end connections. Typically, standard filters can handle up to 10 bar (150 psi) for common sizes. For higher pressures, we can design reinforced structures.
Q4: How do I clean the filter if it gets clogged?
The wedge wire design is self-cleaning during operation. If backwashing is needed, a simple reverse flow or pressure wash will remove accumulated solids. The smooth surface resists particle adhesion.
Q5: Can I order lengths other than 1000 mm?
Yes, we offer custom lengths from 100 mm up to 6000 mm or more. Please specify your required length when ordering.
Q6: What is the open area ratio for a 0.5mm slot width filter?
The open area depends on the wire thickness and support rod spacing. For typical designs, it ranges from 35% to 50%. We can optimize the design to balance strength and flow.
Q7: Do you provide certificates of material or quality?
Yes, we can provide material test certificates (MTC) and inspection reports upon request. Please indicate your requirements when placing an order.
Q8: What is the typical lead time for this product?
Standard lead time is 15–20 working days after order confirmation. For bulk orders or custom designs, please allow additional time.
