Advantages of Johnson wire screen :
1: Vee-Shaped Slots:
Opening shaped like a "V" that open toward the inside of the well tend to allow the particles that are just barely smaller than the width of the slot pass. In other shapes of openings, these particles would get caught in the screen and clog it.
2: Continuous Slots:
The special design gives continuous slot opening across the periphery and length of screen.
3: Very Large Open Area:
This design gives continuous slot and hence the open area for water to enter is more than 2 times that of conventional slotted pipes of any size and slot opening. This allows more water to enter at much lesser frictional head loss and the efficiency of tube well is improved appreciably.
4: Energy Saving:
Due to reduce frictional head losses and increased discharge, the pump load reduces the power required to pump same quantity of water. Power saving of around 20-25% is observed.
