Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in wedge wire screens. Our Stainless Steel Wedge Filter Johnson Filter (1.5m length, 60mm outer diameter) is designed for high-efficiency filtration and robust mechanical strength. With over two decades of expertise, we deliver precision-engineered products that meet rigorous industrial standards, offering reliable performance in demanding environments.
This Johnson filter features a continuous V-shaped wedge wire wound around a support rod, creating a durable, self-cleaning screen. The 60mm OD and 1.5m length make it ideal for water wells, chemical processing, and oil & gas applications. Its slot opening can be customized from 0.1mm to 10mm, ensuring precise particle retention while maintaining high flow rates.
Our manufacturing process uses advanced welding technology to ensure consistent slot width and long service life. The stainless steel material provides excellent corrosion resistance, making the filter suitable for both acidic and alkaline fluids. Below are key technical specifications:
| Parameter | Specification |
| Material | SS304, SS316, SS316L (customizable) |
| Length | 1.5m (other lengths available upon request) |
| Outer Diameter | 60mm (custom diameters from 25mm to 600mm) |
| Slot Size | 0.1mm – 10mm (tolerance ±0.05mm) |
| End Connection | Threaded (NPT/BSP), flanged, or plain |
| Surface Finish | Pickled, polished, or acid-washed |
Key Features & Benefits:
- High Strength & Durability: The wedge wire structure provides excellent mechanical strength, resisting deformation under high pressure and backwash conditions.
- Self-Cleaning Capability: The V-shaped profile allows particles to be easily flushed out during backwashing, reducing maintenance frequency and downtime.
- Precise Filtration: Slot accuracy ensures consistent particle retention, protecting downstream equipment and improving product quality.
- Corrosion Resistance: Stainless steel grades (SS304/316/316L) offer superior resistance to chemical attack and harsh environments, extending service life.
- Customizable Design: Length, diameter, slot size, and end connections can be tailored to specific application requirements, ensuring perfect fit and performance.
- High Flow Capacity: The open area ratio of wedge wire screens is typically 30-50% higher than conventional mesh filters, reducing pressure drop and energy consumption.
Our Johnson filters are widely used in water well screens, chemical industry filtration, petrochemical refining, food & beverage processing, and mining slurry dewatering. The 60mm OD size is particularly suitable for medium-flow applications where space is limited but high filtration efficiency is required.
As a trusted manufacturer, we ensure every filter undergoes strict quality control, including slot size measurement, pressure test, and material verification. Our production capacity exceeds 10,000 meters per month, guaranteeing timely delivery for both small and bulk orders.

Frequently Asked Questions (FAQ)
Q1: What stainless steel grades are available for this filter?
A: We offer SS304, SS316, and SS316L as standard options. For higher corrosion resistance, duplex stainless steel (e.g., 2205) is also available upon request.
Q2: Can the slot size be customized? What is the tolerance?
A: Yes, slot size can be specified from 0.1mm to 10mm. The standard tolerance is ±0.05mm, ensuring consistent filtration performance.
Q3: What is the maximum operating temperature and pressure for this filter?
A: Our wedge wire screens can withstand temperatures up to 400°C (752°F) depending on the material grade. Pressure rating varies with diameter and wall thickness; typically, 60mm OD filters handle up to 10 bar (150 psi). Please consult our engineers for specific conditions.
Q4: How is the filter installed? Are end connections standardized?
A: Common end connections include threaded (NPT or BSP), flanged (ANSI, DIN, JIS), or plain ends for welding. We can also supply custom connections as per your drawing.
Q5: What is the typical lead time for an order?
A: For standard sizes like 1.5m length x 60mm OD, lead time is 7–10 working days. Custom orders may require 15–20 days depending on complexity. We also keep some stock for quick dispatch.
Q6: Do you provide samples before bulk order? How about sample cost?
A: Yes, we offer samples. For existing customers, samples are free; for new clients, a sample fee may apply but will be refunded upon bulk order placement. Shipping cost is at buyer's account.
Q7: Is this filter suitable for backwashing? How often should it be cleaned?
A: Yes, the V-shaped wedge wire design is ideal for backwashing. Cleaning frequency depends on the solid content and flow rate; typically, backwash every 4–8 hours in continuous operation. Our filters are designed to withstand repeated backwash cycles without deformation.
Q8: Can you manufacture filters with non-standard lengths or diameters?
A: Absolutely. We can produce any length from 0.5m to 6m and diameters from 25mm to 600mm. Custom sizes are our specialty. Please provide your requirements for a tailored solution.
