Demister pad, also called mist pad, wire mesh demister, mesh mist eliminator, catching mist, mist eliminator, is used in gas entrained mist separation column to guarantee the filtering efficiency.

When the gas with mist rises at a constant speed and passes through the mesh wire, the rising mist will collide with the mesh wire and attach to the surface filament due to inertia. The mist will diffuse on the filament surface and the droplet will follow along the filaments of the two wire intersection. The droplet will grow bigger and isolate from the filament until the droplets’ weight exceeds the surface tension.
