Features: 1) A well screen is a filtering device that allows ground water from unconsolidated and semi consolidated aquifers to enter the well while at the same time keeping the majority of sand and gravel out of the well and out of the pump 2) A screen also supports the aquifer material and prevents the bore hole from collapsing 3) This well screen is manufactured by wrapping a shaped wire around an internal array of longitudinal rods 4) The wire and rod, generally made from carbon or stainless steel are joined by resistance welding
