Johnson type well screen stainless steel wedge wire screens (customized)

Wire wrapped screens were already developed and in use in the U.S. about 90 years ago. This design makes it possible to adjust the slot width with minimum tolerances to the characteristic grain-size distribution curve of the respective aquifer and manufacture the slots in such a way that an optimal sand removal from the adjoining natural rock is possible.
