Johnson Well Screen Characteristic:
1. Johnson Well Screen with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.
2. Low cost operation Johnson Well Screens with high open area shall favor groundwater infiltration.
Abundant water shall reduce the water level’s down, thus to save energy consumption.
3. Reduce the abrasion of the pump
Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells
Comparatively, groundwater’s entering into screen with higher open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of wells.
