Product Spotlights
Located in Hengshui, Hebei, Anping Xinye Metal Wire Mesh Products Co., Ltd brings over a decade of expertise in manufacturing high-performance filtration solutions. Our 304 Stainless Steel Demister Pad Filter Screen with 150mm thickness is engineered for efficient gas-liquid separation in demanding industrial environments. Crafted from premium 304/304L stainless steel, this demister pad delivers superior corrosion resistance, high mechanical strength, and long service life. Whether you need to remove entrained liquid droplets from gas streams or protect downstream equipment, our product offers a reliable and cost-effective solution.
Product Features & Technical Specifications
- Material Excellence: Made from 304 and 304L stainless steel, ensuring excellent resistance to oxidation, acids, and chlorides. The 304L variant offers improved weldability and reduced carbide precipitation during heat treatment.
- Optimal Thickness: 150mm (approx. 6 inches) provides a deep bed for effective droplet coalescence, maximizing separation efficiency while maintaining low pressure drop.
- Knitted Wire Mesh Structure: The pad is constructed from multiple layers of crimped and knitted wire mesh, creating a tortuous path for gas flow. This design promotes droplet impingement and coalescence, achieving separation efficiencies up to 99% for droplets larger than 10 microns.
- Customizable Dimensions: Available in round, rectangular, or custom shapes to fit your specific vessel or column. Diameter, length, and width can be tailored to your requirements.
- High Temperature & Pressure Resistance: Suitable for operating temperatures up to 450°C (842°F) and pressures up to 10 MPa, depending on mesh density and support structure.
- Easy Installation & Maintenance: Lightweight and flexible design allows for quick installation in new or existing equipment. The pad can be easily cleaned or replaced, reducing downtime.
Typical Applications
- Chemical & petrochemical plants – removal of liquid carryover from distillation columns, absorbers, and scrubbers
- Oil & gas refineries – separation of hydrocarbons from gas streams in flare knock-out drums and separators
- Power generation – moisture removal from steam and exhaust gases
- Pharmaceutical & food processing – clean gas filtration for product integrity
- Environmental protection – mist elimination in air pollution control systems

Frequently Asked Questions (FAQ)
- What is the difference between 304 and 304L stainless steel for demister pads? The main difference is carbon content. 304L has lower carbon (≤0.03%) which reduces the risk of carbide precipitation during welding, making it more suitable for applications requiring high corrosion resistance after welding. Both are excellent for general gas-liquid separation.
- Can this demister pad be used in high-temperature environments? Yes, the 304/304L stainless steel demister pad can withstand operating temperatures up to 450°C (842°F). However, the maximum temperature depends on the specific mesh density and support structure. Please consult with our engineers for your exact operating conditions.
- How do I determine the correct thickness for my application? Standard thickness is 150mm, which works well for most gas-liquid separation tasks. Thinner pads (100mm) offer lower pressure drop but may reduce efficiency, while thicker pads (200mm or more) increase separation efficiency at the cost of higher pressure drop. We recommend providing your gas velocity, droplet size, and required efficiency for a customized recommendation.
- Is the demister pad supplied with a support grid? The pad itself is flexible and requires a support grid (e.g., grating or perforated plate) to hold it in place. We can supply compatible support grids or recommend a suitable design. Please specify if you need a complete assembly.
- What is the typical lifespan of this demister pad? Lifespan depends on operating conditions such as temperature, corrosive environment, and solid particle content. Under normal conditions, a 304 SS demister pad can last several years. Regular cleaning can extend its service life. Replace the pad when visible damage or significant performance drop occurs.
- Can you customize the size and shape to fit my existing vessel? Absolutely. We can manufacture demister pads in any shape (round, rectangular, elliptical, etc.) and dimensions to match your vessel. Simply provide a drawing or detailed measurements, and we will produce accordingly.
- How is the demister pad packaged for export? Each pad is securely rolled or folded, wrapped in protective material, and packed in a sturdy wooden or carton box to prevent deformation during transit. For large orders, we use palletized packaging with steel straps.
- Do you offer samples for testing? Yes, we can provide small samples (e.g., 300mm x 300mm) for your evaluation. Please contact our sales team with your requirements. Sample cost and shipping may apply.
