High-Efficiency Wire Mesh Mist Eliminator for Industrial Gas-Liquid Separation
In demanding industrial processes where gas streams carry entrained liquid droplets, efficient separation is critical for equipment protection, process efficiency, and environmental compliance. Our wire mesh mist eliminator is engineered to deliver superior performance in these challenging applications. Constructed from high-quality metal or plastic wires woven into a dense, porous pad, this demister pad acts as a coalescing filter, capturing fine mist and aerosols as small as 3-5 microns with exceptional efficiency. Ideal for scrubbers, distillation columns, evaporators, and knock-out drums, our solution ensures cleaner gas output, maximizes product recovery, and safeguards downstream components.
Key Features of Our Wire Mesh Mist Eliminator
Our demister pads are not just standard filters; they are precision-engineered components designed for reliability and longevity in harsh conditions.
- High Surface Area & Porosity: The intricate knitted structure provides a vast surface area for droplet impingement while maintaining over 99% void space, ensuring minimal pressure drop and high gas throughput.
- Superior Coalescing Efficiency: Effectively captures sub-micron to large droplet sizes, achieving removal efficiencies often exceeding 99.9% for droplets above 10 microns, leading to cleaner operations.
- Robust Construction Materials: Available in a wide range of materials including 304/316 stainless steel, PP, PTFE, and alloy wires to resist corrosion, high temperatures, and chemical attack.
- Customizable Design: We tailor pad thickness, density, mesh style, and overall dimensions to match your specific process conditions, vessel geometry, and separation requirements perfectly.
- Easy Installation & Maintenance: Designed as drop-in units or custom-assembled sections for easy installation into existing or new vessels. They are cleanable and reusable in many applications.

Frequently Asked Questions (FAQ)
How do I select the right material for my application?
Material selection is critical and depends on the chemical composition, temperature, and presence of corrosive elements in your gas stream. We guide you through this choice, commonly recommending SS316 for chlorides, PP for acids at moderate temps, or PTFE for highly aggressive chemicals.
What is the typical delivery lead time?
For standard sizes and materials, lead time is typically 2-4 weeks. Custom designs or large projects may require additional time. We provide accurate timelines upon review of your specifications.
Can you supply the mist eliminator with supporting grids or hardware?
Yes. We are a full-service provider and can manufacture and supply all necessary support grids, hold-down bars, edge seals, and complete assembly units ready for installation into your vessel.
How do I determine the correct pad thickness and density?
This is based on droplet size distribution, required efficiency, and allowable pressure drop. Thicker, denser pads capture finer mist but increase pressure drop. Our engineering team uses proprietary sizing software and experience to recommend the ideal configuration.
Is the wire mesh mist eliminator cleanable and reusable?
In most applications, yes. For fouling services, pads can often be cleaned via washing, steaming, or gentle chemical cleaning. In extremely fouling or polymerizing services, a disposable element might be recommended. We advise based on your specific process.
