Johnson wire screens (Johnson Type Water Well Screens) are manufactured by VEE or the wedge shaped wire around an internal array of longitudinal support rods. The advanced all-weld technology is used with each intersecting point of these wire fusion welded, which creates robust construction and excellent mechanical performance.
The VEE or wedge shaped profile wire wraps around support rods over full length of the screen creating a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well. The slots can be changed according to different strata.
Diameters: 10-3/4", Also can make 4-1/2", 6-5/8", 8-5/8", 12-3/4", 14", 16" etc.

- Non-clogging construction: Creates continuous slots that avoid blockage and ensure unimpeded water flow.
- Large filtering area: Wider open area reduces water entry speed, preventing sand from entering under pressure, improving water yield and service time.
- Long service life: Robust construction ensures extended durability.
- Excellent construction strength: Superior pressure-resistant performance.
- Customizable: Specifications and end connections can be fabricated according to customer requirements.
