Defender Cable Rake Bar Screen

Johnson Screens^® Defender Cable Rake Bar Screen is a vertical, cable driven coarse screen suitable for screening of sewage or raw water.

The screen is typically installed in a pumping station or at the inlet of sewage or water treatment plants; The submerged section in contact with the influent is a series of parallel bars that make up the fixed bar screen. These parallel bars retain solids greater than the bar spacing as the influent flows through. The retained solids are then extracted by means of a cable-driven, raking system which lifts the solids outside the channel and discharges into a hopper.

The raking system comprises of a bucket with teeth on one side and supported by three cables and is activated by the water level differential in the channel.
