As a manufacturer with over 25 years of experience in the wire mesh industry, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Johnson Wedge Filter specifically designed for the petrochemical industry. This filter features a precise 0.1mm slot made from 304 stainless steel, offering exceptional corrosion resistance and durability in harsh chemical environments. Our wedge filters are engineered to provide reliable solid-liquid separation, ensuring optimal performance in refining, chemical processing, and oil & gas applications.
The unique wedge wire construction allows for a smooth, self-cleaning surface that minimizes clogging and reduces maintenance downtime. With a slot size of just 0.1mm, it effectively retains fine particles while maintaining high flow rates. Whether you need a filter for catalyst recovery, feedstock filtration, or wastewater treatment, this Johnson wedge filter delivers consistent results.
Below we provide a detailed breakdown of the product features, technical specifications, and benefits to help you understand why our filter is the preferred choice for petrochemical plants worldwide.
Key Features & Benefits
- Precision 0.1mm Slot: Ensures accurate particle separation, capturing fine solids while allowing liquids to pass efficiently.
- 304 Stainless Steel Construction: Offers excellent resistance to corrosion, oxidation, and high temperatures, suitable for aggressive petrochemical media.

Frequently Asked Questions
Q1: What is the typical lifespan of a 304 SS Johnson wedge filter in petrochemical service?
A: The lifespan depends on operating conditions, but with proper maintenance, our filters typically last 3–5 years in moderate environments. In aggressive chemical streams, we recommend periodic inspection; our team can provide replacement schedules based on your process parameters.
Q2: Can the slot size be customized to other values?
A: Yes, we offer slot sizes from 0.05mm to 5mm. The 0.1mm is a standard option, but we can manufacture any slot width within our capability. Please provide your required particle retention size.
Q3: Is the filter suitable for high-temperature applications?
A: 304 stainless steel can handle temperatures up to 400°C (752°F) in oxidizing environments. For higher temperatures, we recommend 310S or Inconel alloys. Contact us for specific temperature requirements.
Q4: How do I clean the wedge filter?
A: The self-cleaning design reduces clogging, but periodic backwashing with clean liquid or gas is effective. For stubborn deposits, chemical cleaning or ultrasonic cleaning can be used. Avoid using abrasive tools that may damage the wire profile.
Q5: What are the available end connections?
A: We offer flange (ANSI, DIN, JIS), threaded (NPT, BSP), and weld-end connections. We can also provide custom end caps or adapters as per your drawing.
Q6: Can you provide a pressure drop curve for this filter?
A: Yes, we can calculate pressure drop based on flow rate, fluid viscosity, and slot geometry. Our technical team will provide a detailed curve upon request with your operating conditions.
Q7: Is this filter suitable for corrosive media like sulfuric acid?
A: 304 SS has limited resistance to sulfuric acid at low concentrations and temperatures. For highly corrosive media, we recommend 316L or duplex stainless steel. Please provide the chemical composition and temperature for a material recommendation.
Q8: What is the minimum order quantity (MOQ)?
A: Our MOQ is 10 pieces for standard sizes, but we accept smaller trial orders for first-time customers. For custom designs, MOQ may vary. Please contact our sales team for details.
