Demister wire mesh is a type of wire mesh that is designed to remove mist or fog from a gas stream. It consists of a series of closely spaced wires that are woven or welded together to form a mesh. As the gas passes through the mesh, the mist droplets or fine particles in the gas come into contact with the wires and are trapped, allowing the clean gas to pass through. Demister wire mesh is commonly used in industries such as chemical processing, oil refining, and power generation where mist or fog can be a problem.
