1.Each slot opening of water well screen cylinder between adjacent wires is V-shaped,
resulting from the special shape of the wire used to form the screen surface.
2.The V-shaped opens, designed to be nonclogging, are narrowest at the outer face and widen inwardly.
3.Continuous-slot Johnson deep well screens provide more intake area per unit area of screen surface than any other type.
4.For any given slot size, this type of screen has maximum open area.
1. It has high mechanical strength, can bear large pressure drop.
2. It has equal slots for filtering, can form equally distributed filter cake, easy to clean for reuse.
3. The wedge type slot can improve backflushing and regeneration performance.
4. It has resistance to pressure, temperature, aging, corrosion, can be applied for different kinds of fluid.
