All-welded continuous slot Johnson type well screens
Johnson type well screens produced by OASIS has a high open area compared with other screen media, then this kind of water well screens allows lower entrance velocity and higher flow rates through the screen. Johnson type well screens give continuous slot openings that widen inwardly. This makes the screen self-cleaning by allowing "near slot size" particles to pass through the screen rather than plug the opening.
