Coanda Screen
Curved wedge wire panel that exploits the Coanda effect for passive water intake. Water flows over the curved surface and adheres to the wire, passing through the slots by gravity and surface tension. Debris is rejected over the screen face. No moving parts, no power consumption, no operator intervention. Ideal for hydropower, remote water supply, irrigation, and aquaculture. Available in three standard sizes: 450mm, 700mm, and 1270mm Height. Custom dimensions available for project-specific applications.
APPLICATIONS
• Hydropower intake
• Irrigation canal intake
• Remote water supply
• Aquaculture water supply
