Advantage of Johnson Type Downhole Slotted Well Screen Filter Tube:

As already known, Johnson Type Downhole Slotted Well Screen for water well,, have, with equal diameter and slot, bigger opening surfaces than the ones of other kinds of screens (bridge or simple slot screen).
The higher percentage of opened area enlarges the profit of water. In Johnson Downhole Slotted Well Screens, the wide opened area simplifies enormously (in comparison with other screens) the washing of the well when, for instance, it is necessary to eliminate the mud panel.
In favour of the spiral Johnson type screens there is the chance to have smaller slots than the ones of other kinds of screen.
This is a great advantage when you have to filter waters in slimy soils where it is therefore necessary that the drain is of a very low grain size and that, at the same time, it cannot pass through the screen for water well itself.
Moreover, in rotation perched wells by inverted circulation, if the hollow space hole/casing is very small and such not to allow the forming of artificial drains,
it is better to employ these Johnson type screens with slots of 0,20 mm.
