Invented by BEAUDREY in 1926 and used mainly for medium and large capacity plants, the drum screen is a self-cleaning millimetric mesh aperture screen. It is the most reliable type of rotating screen as it has only one moving part: the drum motor.

 

Fully automatic, capable of the very largest flow rates (up to 35 m3/sec), the drum screen is installed in a concrete chamber.

 

It is installed in power stations, LNG and petrochemical plants, desalination plants, drinking water and irrigation plants.

 

The drum screen is available for two types of flow patterns: from the outside towards the inside and from the inside towards the outside.
