Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export turnover of US$5 million – US$10 million. Our Stainless Steel Scraper Filter Element (Johnson Filter) is engineered for demanding petrochemical solid-liquid separation applications. Crafted from premium stainless steel and featuring a robust Johnson-type wedge wire construction, this filter element delivers exceptional durability, high flow rates, and reliable scraper cleaning performance. Whether you need to separate catalyst fines, polymer solids, or abrasive particles, our filter elements are designed to maximize uptime and minimize maintenance costs.
Key Features & Technical Specifications
- Material Excellence: Made of 304 or 316L stainless steel, offering superior corrosion resistance against aggressive chemicals and high temperatures up to 400°C (depending on material grade).
- Johnson Wedge Wire Design: Continuous V-shaped wire wrapped around support rods creates a slot opening that resists clogging and allows easy backwashing or scraper cleaning.
- High Mechanical Strength: The all-welded construction ensures the element withstands high differential pressure, vibration, and thermal shock common in petrochemical processes.
- Customizable Filtration Precision: Slot widths from 0.05mm to 5mm (50μm – 5000μm) are available to match your specific solid-liquid separation requirements.
- Scraper Compatibility: The smooth outer surface and precise slot geometry are optimized for use with rotary or reciprocating scraper mechanisms, ensuring continuous cleaning without damage.
- Versatile Connection Options: Flanged, threaded, or custom end caps to fit existing filter housings from major OEMs.
- Extended Service Life: Our elements are designed for long-term operation in harsh environments, reducing replacement frequency and total cost of ownership.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a Johnson filter element and a standard wedge wire screen?
A: A Johnson filter element typically refers to a continuous slot wedge wire screen used in scraper-type filters, while standard wedge wire screens may be used in static applications. Our element is specifically designed with a smooth outer surface and precise slot geometry to work with rotating or reciprocating scraper blades. -
Q: Can you manufacture filter elements with non-standard dimensions?
A: Yes, we offer full customization. Provide your required outer diameter, length, slot width, end connection type, and material grade, and we will produce accordingly. -
Q: What is the maximum operating temperature for your stainless steel scraper filter element?
A: For standard 304 SS, the maximum continuous temperature is around 400°C; for 316L, it is similar. If you need higher temperature resistance, we can recommend other materials (e.g., Duplex or Inconel) upon request. -
Q: How do you ensure the slot width accuracy?
A: We use precision winding machines and perform 100% visual inspection. Slot width tolerances are typically within ±0.02mm, and we can provide a test certificate upon request. -
Q: Are these filter elements compatible with existing scraper filter housings from major brands?
A: Yes, we can match the end connections (flange, thread, or custom) of most standard housings. Please provide the housing model or drawing for a perfect fit. -
Q: What is the typical lead time for custom orders?
A: For standard sizes, lead time is 15–20 working days. For fully custom designs, it may be 25–35 working days, depending on complexity and quantity. -
Q: Do you offer samples for testing?
A: Yes, we can provide sample elements for evaluation. The sample cost is usually refundable with a bulk order. Please contact us for details. -
Q: How should I store and maintain the filter element?
A: Store in a dry, clean environment. For cleaning, chemical or ultrasonic cleaning is recommended. Avoid using sharp tools that can damage the slot edges. Regular inspection of the scraper blades is also advised to prevent wear on the element.
