Water well screen is welded by V wire and support rod. There is a fixed value slot between each V wire, and the continuous slot is designed to provide maximum open area to reduce entrance velocity, increase hydraulic efficiency and promote more effective development. The wrapped wire is V shape, and the support rod is O shape. Filter from outside to inside.
Filter out the impurities and suspended matter in the water to ensure that the water is clean and sanitary and will not cause blockage. Screens are typically made of fine-mesh stainless steel mesh that effectively removes sediment, sediment, and other small particles from the water. The design and placement of wire-wound screens can be adjusted to ensure a balance between water flow and filtration.

- Not easy to jam: The special V shaped wire makes the hole of screen outside face smaller than inside, so the hole is not easy to jam.
- Slot even: The CNC machine tools strictly control the gap between the wire, so that the gap is even.
- Strong corrosion resistance: Stainless steel 304 has high corrosion resistance.
Johnson Screens specific continuous-slot construction aims to optimize flow rates, minimize clogging and help develop the water-bearing geological formations faster. It is best applied in the following situations:
- Geological formations comprised of small, fine particles
- Water wells where gravel packs will be installed
- Thin aquifers, where maximum open area is required
- Large- and small-diameter deep wells
