Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with an annual export value of US$5 million to US$10 million. Our Stainless Steel Scraper Filter Element, Johnson Filter Type is engineered for demanding solid-liquid separation applications. With a 1.2mm slot width and 100 micron filtration rating, this element delivers precise particle retention while maintaining high flow rates. The IP65 rated design ensures reliable performance in wet or dusty environments. Backed by years of wire mesh expertise, we offer durable, reusable filter elements that reduce downtime and operating costs.
Key Features & Technical Specifications
- Johnson (Wedge Wire) Construction: Continuous V-shaped wire wound on support rods, providing a strong, self-cleaning surface ideal for scraper systems.
- Slot Width: 1.2mm – Balanced for coarse screening and fine filtration. The 100 micron retention level captures particles effectively without clogging.
- Stainless Steel Material: Available in SS304, SS316L – excellent corrosion resistance against acids, alkalis, and high temperatures.
- IP65 Rating: Dust-tight and protected against water jets – suitable for outdoor or washdown environments.
- Customizable Dimensions: Outer diameter, length, and end connections can be tailored to fit your existing scraper filter housing.
- High Mechanical Strength: Withstands pressure differentials and mechanical scraper action without deformation.
- Easy Cleaning & Reusability: Backwash or brush scraper efficiently removes trapped solids, extending service life.

Frequently Asked Questions
Q1: What is the difference between slot width and micron rating? Can a 1.2mm slot filter 100 micron particles?
A: Slot width (1.2mm) is the physical gap between wires, which typically retains particles larger than 1.2mm. However, the Johnson filter element can achieve a 100 micron filtration rating through a combination of slot geometry and surface roughness, or by using a multi-layer design. We recommend confirming your required retention size with our engineers to ensure the correct configuration.
Q2: Is this filter element compatible with all scraper filter systems?
A: The Johnson type scraper element is designed to fit most standard scraper filters, but we recommend providing your housing dimensions (OD, length, end connection type) to confirm compatibility. We can customize the element to match your existing equipment.
Q3: What stainless steel grades are available, and which is best for corrosive environments?
A: We offer SS304 (general purpose) and SS316L (enhanced corrosion resistance). For applications involving chlorides, acids, or seawater, SS316L is recommended. Both are available and can be specified in your order.
Q4: How often does the filter element need to be replaced?
A: With proper scraper cleaning and backwash, the element can last several years. The lifespan depends on the abrasiveness of the solids, chemical compatibility, and operating pressure. Many customers report 3–5 years of service before replacement is needed.
Q5: Can you provide samples for testing before bulk order?
A: Yes, we offer sample pieces (customized to your dimensions) for a nominal fee. The sample cost is deducted from your first bulk order. Please contact us to discuss your testing requirements.
Q6: What is the IP65 rating? Does it mean the element is waterproof?
A: IP65 means the housing (or the element if it includes a sealed assembly) is completely dust-tight and protected against water jets from any direction. It is suitable for washdown environments but not for submersion. If your application requires submersion, please specify when ordering.
Q7: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 10 pieces. For custom dimensions, MOQ is 50 pieces. We can negotiate lower quantities for sample orders or first-time collaboration.
