2). Most manufacturers recommend 100 to 200 mesh screens for drip irrigation system. Normally, the discharge through the screens is less than 135 lps per square meter of screen openings. A standard 200 mesh stainless steel screen has only 58% open area and equivalent nylon mesh with same size opening has only 24% open area. In screen filter, the mesh size and the total open area determine the efficiency and operational limits. 2: Specifications of filter screens.
