Mesh filters are devices used to separate solids from liquids or gases by using a mesh material. They consist of a network of interconnected strands that create small openings, allowing fluid to pass through while trapping larger particles. This makes them useful in various applications, such as water treatment, industrial processes, and air filtration. These filters come in different sizes and materials, depending on the specific needs of the application. Common types include stainless steel mesh filters and nylon mesh filters, each offering unique benefits like durability and resistance to corrosion. Proper maintenance of mesh filters is essential for optimal performance.
