The Noggerath® Overflow Screen OVF is composed of a semi-cylindrical screen panel with an internal conveying/cleaning screw.

The spiral screw is automatically activated based on water level to convey the solids to the discharge zone. Cleaning brushes fixed to the flight edges of the spiral will clean the screen panel surface.
