Wedge Wire Screen Filter is manufactured with V-shaped profile wire, which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded.

The pitch of winding gives different spacing between two adjacent turns of wire. This spacing gives passage for water to enter. The entire process is completed on fully computerized machines.

• V-Shaped Slots: Openings shaped like a "V" that open toward the inside of the well allow particles that are just barely smaller than the width of the slot to pass, preventing clogging.
• Continuous Slots: Special design provides continuous slot opening across the periphery and length of screen.
• Very Large Open Area: Design offers more than 2 times the open area of conventional slotted pipes, allowing more water to enter with less frictional head loss.
• Better Sand Filtration: Wide range of slot openings available down to 0.15mm for proper slot selection based on sand size in specific areas, improving sand control and reducing pump maintenance.
