Key Features & Technical Specifications
- Material: 316L Stainless Steel – excellent corrosion resistance, especially in acidic and chloride environments, extending service life.
- Plate Thickness: 2.0mm – provides structural rigidity to withstand vacuum pressure and mechanical stress during operation.
- Mesh Size: 20μm (microns) – ensures fine particle retention while maintaining high flow rates, ideal for dewatering and clarification.
- Angle: 18° sector design – optimized for disc vacuum filters, ensuring maximum coverage and efficient cake discharge.
- Fabrication: Precision laser-cut or stamped with smooth edges, reducing risk of mesh damage and improving sealing.
- Surface Finish: Available in polished or mill finish; polished option reduces fouling and facilitates cleaning.
- Customization: Dimensions, hole patterns, and attachment features can be tailored to fit specific filter models.
| Parameter | Specification |
|---|---|
| Material Grade | 316L (UNS S31603) |
| Mesh Opening | 20 μm (0.02 mm) |
| Wire Diameter (Approx.) | 0.025 – 0.03 mm (depending on weave) |
| Open Area | ~30% – 40% (optimized for flow vs. retention) |
| Operating Temperature | Up to 400°C (in non-oxidizing environments) |
| Max Pressure Differential | 0.5 – 0.8 MPa (dependent on support structure) |
Advantages & Benefits for Your Process
- Enhanced Filtration Efficiency: The 20μm mesh effectively captures fine solids, improving cake purity and reducing downstream load.
- Long Service Life: 316L stainless steel resists pitting, crevice corrosion, and stress cracking, even in harsh chemical environments.
- Reduced Downtime: Robust 2.0mm plate minimizes deformation under vacuum, maintaining consistent performance over time.
- Easy Installation: Precision-cut sectors fit standard disc vacuum filter frames with minimal modification; customized mounting holes available.
- Cost-Effective: High open area and low pressure drop reduce energy consumption, while durability lowers replacement frequency.
- Versatile Applications: Suitable for dewatering in mining (coal, iron ore), chemical processing, food & beverage, and municipal wastewater treatment.
Our 18° filter sectors are manufactured under strict quality control, with each unit inspected for mesh integrity, dimensional accuracy, and weld quality. We offer samples for testing to ensure compatibility with your existing equipment.

Frequently Asked Questions (FAQ)
-
Q: What is the exact mesh opening tolerance for the 20μm filter sector?
A: Our standard tolerance is ±2 μm, ensuring consistent filtration performance. For tighter tolerances, please contact us for custom options. -
Q: Can this sector be used with disc vacuum filters from other manufacturers?
A: Yes, the 18° sector is a common design. We can adjust dimensions (radius, chord length, hole pattern) to fit your specific filter model. Please provide your filter’s drawing or specifications. -
Q: Is the 316L stainless steel suitable for food-grade applications?
A: 316L is generally considered food-contact safe, but we recommend confirming compliance with local regulations (e.g., FDA, EU). Our sectors can be supplied with a polished surface finish for easier cleaning. -
Q: What is the typical lead time for production?
A: For standard sizes, lead time is 15–20 working days. Custom orders may require 25–30 working days, depending on complexity. -
Q: Do you offer samples before bulk order?
A: Yes, we provide samples for evaluation. Sample cost is negotiable, and shipping is at the buyer’s expense. We can also produce a small batch for trial. -
Q: How is the mesh attached to the 2.0mm plate?
A: The mesh is welded or bonded to the support plate using a continuous seam, ensuring leak-free performance. The attachment method can be customized based on your process requirements. -
Q: What is the maximum operating temperature for this sector?
A: 316L stainless steel can withstand up to 400°C in non-oxidizing conditions. However, the actual limit depends on the sealing material and filter design. We recommend consulting our technical team for high-temperature applications. -
Q: Do you provide international shipping and what are the payment terms?
A: We ship from multiple Chinese ports (Tianjin, Qingdao, etc.). Payment terms are typically T/T (30% deposit, 70% before shipment) or L/C at sight. We can also discuss other options for long-term cooperation.
