Plastic Wire Mesh Mist Eliminator Product Description

Plastic Wire Mesh Mist Eliminator is a high-performance gas-liquid separation device engineered specifically for severely corrosive environments. Manufactured from knitted PP, PTFE, PVDF, or PE monofilament wire mesh, it is formed into pads of various thicknesses and shapes for installation in scrubbing towers, absorption columns, and chemical processing equipment. When gas carrying entrained liquid droplets passes through the intricate knitted mesh, the droplets impinge on the wire surfaces, coalesce into larger drops, and drain away by gravity—achieving removal efficiencies exceeding 99% for droplets above 3–5 microns. Its all-plastic construction provides absolute immunity to corrosion, making it the essential choice in acid pickling, electroplating, chlorine processing, and semiconductor-grade chemical production.

Product Highlights

Universal Corrosion Resistance: Available in PP, PTFE, and PVDF, the all-plastic construction resists all acids (including HF and aqua regia), strong alkalis, and chlorinated solvents, ensuring indefinite service life where stainless steel and alloy demisters would be destroyed.
High Separation Efficiency: The dense knitted mesh structure achieves 99%+ removal efficiency for mist droplets above 3–5 microns, effectively eliminating acid mist carryover, protecting downstream equipment, and reducing chemical emissions.
Low Pressure Drop: The high-voidage (92–98%) knitted structure introduces minimal resistance to gas flow, reducing fan power consumption and ensuring stable column operation.
Lightweight & Easy Installation: Weighing approximately 1/8 of equivalent metal demisters, the plastic pads are easy to handle, cut, and install, with options for round, annular, or rectangular shapes to fit any vessel configuration.
Anti-Stick & Easy to Clean: The smooth, non-wetting PTFE and PP surfaces resist scaling and fouling, reducing maintenance frequency and allowing easy on-site cleaning when required.
Custom Fabrication: Pads can be manufactured in thicknesses from 100mm to 500mm, with custom diameters up to several meters, and optionally combined with grids or support rings for structural rigidity.
