As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Stainless Steel Wedge Johnson Filter – a high-performance filtration solution engineered for durability and precision. Made from genuine 304 stainless steel, each filter is supplied with a Mill Test Report to guarantee material quality, and backed by a 1-year warranty for your peace of mind. Our wedge wire construction delivers superior strength, self-cleaning capability, and consistent slot accuracy, making it the ideal choice for demanding industrial applications.
This filter is designed to withstand harsh environments, including high pressure, corrosion, and abrasion. The V-shaped wire profile creates a continuous slot that minimizes clogging and ensures efficient backwashing. Whether you need it for water well screens, sand control, or process filtration, our Johnson filter offers reliable performance with minimal maintenance.
Key Features & Benefits
- Precision Slot Design: The wedge wire is wound around support rods with precise spacing, providing a uniform slot opening that prevents particles from passing through while allowing high flow rates.
- High Mechanical Strength: The continuous wedge wire and robust support structure can withstand high pressure differentials and heavy load conditions.
- Self-Cleaning Capability: The V-notch profile makes it easy to backwash, reducing downtime and extending service life.
- Corrosion Resistance: 304 stainless steel offers excellent resistance to rust, chemicals, and chloride environments (with optional 316L available upon request).
- Mill Test Report Included: Each filter comes with a material certificate confirming the chemical composition and mechanical properties of the stainless steel.
- 1-Year Warranty: We stand behind our product quality and offer a full replacement or repair warranty for manufacturing defects.
- Customizable Dimensions: Slot size, wire diameter, length, and outer diameter can be tailored to your specific requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a Johnson filter and a standard wedge wire screen?
A: A Johnson filter uses a continuous V-shaped wire wound around longitudinal support rods, providing a stronger, self-cleaning structure compared to simpler screens. It is specifically designed for downhole and high-pressure filtration. -
Q: Can I get a custom slot size that is not listed?
A: Yes, slot sizes from 0.1mm to 10mm are available, and we can produce any intermediate size based on your requirements. Please specify your desired gap. -
Q: Is the Mill Test Report provided for every batch?
A: Yes, we include a Mill Test Report (MTR) with each shipment, confirming the chemical composition and mechanical properties of the 304 stainless steel used. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, it is 15–20 working days. Custom dimensions may require 25–30 working days, depending on complexity and quantity. We can expedite for urgent orders upon request. -
Q: Can this filter be used in high-temperature environments?
A: 304 stainless steel can withstand temperatures up to 870°C (in intermittent service) and 925°C in continuous service. For higher temperatures, we recommend 316L or 310S stainless steel. -
Q: How do I clean the filter?
A: The wedge design allows for backwashing or flushing. For heavy fouling, chemical cleaning or ultrasonic cleaning is also effective. The filter is resistant to most cleaning agents. -
Q: Do you offer any warranty on the product?
A: Yes, we provide a 1-year warranty against manufacturing defects. If you encounter any issue within that period, we will replace or repair the filter at no extra cost. -
Q: What pack sizes are available?
A: Filters are typically packed individually in wooden crates or cartons to prevent damage during transit. Bulk packaging is also available for large orders.
