The Mesh Pad Mist Eliminator is designed to capture and remove fine liquid droplets from vapor streams. It consists of a knitted wire mesh structure, which provides a large surface area for droplets to collide and coalesce. As the vapor passes through the mesh, liquid droplets as small as 3 to 5 microns adhere to the wire filaments, gradually forming larger droplets. These droplets then drain off under gravity, preventing liquid carryover and ensuring cleaner vapor. Mesh pad mist eliminators are widely used in distillation columns, evaporators, and separators, offering high-efficiency mist elimination with minimal pressure drop.
S-Cube mesh demisters consist of a pad of knitted metal or plastic wire mesh, usually sandwiched between grids for mechanical support.
- Snug Fit Construction: Pads are cut slightly oversized to eliminate vapor bypass, ensuring maximum efficiency.
- Optimized Mesh Structure: Each mesh pad is made from crimped layers of monofilament fabric, to provide uniform voidage and a high surface-to-volume ratio for effective mist removal.
- Structural Stability: The top and bottom grids are connected using spacer rods, welded to each grid to maintain dimensional integrity.
- Heavy-Duty Options: Where required, reinforced support grids can be provided, ensuring extra durability and allowing the demister to function as a working platform inside the vessel.

FAQs
S-Cube wire mesh mist eliminators can remove up to 99% of mist droplets as small as 3-5 microns, depending on the mesh style and operating conditions. The efficiency varies with the mesh density, wire diameter, and gas velocity.
S-Cube offers wire mesh mist eliminators in various materials including stainless steel (SS304, SS316), PTFE (Teflon), polypropylene, and special alloys like nickel-based alloys for harsh environments. Material selection depends on chemical compatibility and operating conditions.
Wire mesh mist eliminators have a low pressure drop, typically ranging from 10-50 mm of water column depending on the mesh style, thickness, and gas velocity. The SCM series is designed to minimize pressure drop while maintaining high efficiency.
Mesh style selection depends on several factors: droplet size to be removed, gas velocity, fouling potential, and service conditions. SCM-A series is for high efficiency in clean service, SCM-B for general purpose, and SCM-C for fouling services. Our technical team can help you select the appropriate style.
Standard wire mesh pad thickness ranges from 100mm to 200mm, with 150mm being the most common. Thicker pads provide higher efficiency but also higher pressure drop. The thickness should be selected based on the required efficiency and acceptable pressure drop.
Yes, wire mesh mist eliminators are available in corrosion-resistant materials like PTFE, polypropylene, and special alloys. The SCM-PP series is specifically designed for acid mists and corrosive services, while SCM-T (Teflon) is suitable for very corrosive environments.
Maintenance frequency depends on the application and fouling potential. In clean services, mesh pads can operate for years without maintenance. In fouling services, periodic cleaning or replacement may be required. Regular inspection is recommended to ensure optimal performance.
