Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in wire mesh products. With an annual export value of US$5-10 million and a global market presence spanning North America, Europe, Asia, and beyond, we bring decades of expertise to every product. Our 304 Stainless Steel Demister Filter Disc (0.5mm Mesh) is engineered for efficient industrial gas-liquid separation, offering reliable performance in demanding environments. Crafted from high-quality 304 stainless steel, this demister disc effectively removes entrained liquid droplets from gas streams, protecting downstream equipment and improving process efficiency.
The demister filter disc features a precision-woven 0.5mm mesh that provides optimal balance between separation efficiency and pressure drop. The knitted wire mesh structure creates a large surface area for droplet coalescence, allowing liquid particles to agglomerate and drain away. Each disc is customizable in diameter and thickness to fit your specific column or vessel requirements. Whether used in chemical processing, petrochemical refineries, natural gas treatment, or environmental protection systems, our demister disc delivers consistent, long-lasting performance.
Product Features & Benefits
- High Separation Efficiency: The 0.5mm mesh captures droplets as small as 1-3 microns, achieving up to 99.9% separation efficiency under optimal conditions.
- Corrosion Resistance: 304 stainless steel ensures excellent resistance to moisture, acids, and alkalis, extending service life in harsh industrial environments.
- Low Pressure Drop: Specially designed knitted structure minimizes resistance to gas flow, reducing energy consumption and operational costs.
- Customizable Dimensions: Available in diameters from 50mm to 5000mm and thicknesses from 100mm to 150mm (or custom), to fit any column or scrubber.
- Easy Installation: Lightweight yet sturdy, the disc can be mounted directly onto support grids or welded frames, simplifying maintenance.
- Anti-Clogging Design: Open mesh structure prevents fouling and allows self-cleaning, reducing downtime for cleaning.
- Wide Temperature Range: Suitable for operating temperatures from -20°C to 400°C, adaptable to various process conditions.

Frequently Asked Questions (FAQ)
1. Can the demister disc be custom-sized to fit my column?
Yes, we offer full customization. You can specify the exact diameter, thickness, and mesh density. We can produce discs from 50mm to 5000mm in diameter, and thicknesses from 50mm to 300mm. Please provide your vessel’s internal dimensions for a precise fit.
2. What is the maximum operating temperature for 304 stainless steel demister?
304 stainless steel demister discs can operate continuously at temperatures up to 400°C (752°F). For higher temperature applications, we recommend 310S or Inconel alloys.
3. How do I install the demister filter disc?
The disc is typically placed on a support grid inside the column or vessel. It can be held in place by a retaining ring or welded clips. We can also provide installation instructions and recommend appropriate support designs.
4. What is the pressure drop across the disc?
Pressure drop depends on gas velocity, disc thickness, and density. For a standard 150mm thick disc at 1 m/s superficial gas velocity, the pressure drop is approximately 0.1–0.3 kPa. We can provide detailed calculations based on your operating conditions.
5. How often does the demister need cleaning or replacement?
With proper design, the self-draining nature of the mesh minimizes clogging. Cleaning intervals depend on the process fluid’s fouling tendency. In clean applications, the disc can last for years. Periodic wash with water or steam can restore performance.
6. Do you offer samples for testing?
Yes, we can provide small sample discs (e.g., 100mm diameter) for evaluation. Please contact our sales team with your requirements. Sample costs are negotiable and may be waived for serious inquiries.
7. What certifications do you have for quality control?
We follow strict internal quality control procedures. Our factory is equipped with testing equipment for mesh count, wire diameter, and material composition. We can provide material test certificates upon request. While we do not hold specific third-party certifications, our products meet international standards for industrial wire mesh.
8. Can I use this demister for liquid-liquid separation?
This product is designed for gas-liquid separation. For liquid-liquid separation (e.g., oil-water), we recommend our coalescer media or mesh pads with different wettability. Please consult our technical team for the best solution.
