The very large opening, combined with a floating head, facilitates mostly polluted surface water intake, enabling a more effective treatment.

The flap automatically adjusts to the water level; it does not cause irritating noises, and is visually quite pleasant. Its particular position, close to the swimming pool wall, ensures operation similar to a section of the perimeter overflow edge.

An innovative product enables the swimming pools to be built with a new and improved appearance, as well as more effective water treatment.
