Advantages:
Not easy to jam
the special V shaped wire, make the hole of screen outside face is smaller than inside, so the hole is not easy to jam.
Slot even
The CNC machine tools strictly control the gap between the wire, so that the gap is even.
Strong corrosion resistance
Stainless steel 304 have the high corrosion resistance
Application:
Continuous slot screen is best applied in the following situations:
Geological formations comprised of small, fine particles
Water wells where gravel packs will be installed
Thin aquifers, where maximum open area is required
Large- and small-diameter deep wells
