PM Over-screens are comparable to traditional Wire Mesh Over-screens. They are available with similar opening sizes and open area percentages as wire cloths, but the materials of construction are very different. The material used to make PM Over-screens is punched from stainless steel; it is not made up of individual wire cloth.
The PM Over-screen cylinder ends are hemmed to provide a smooth, finished edge for the strainer element. All material is T316 stainless steel.
