Self-cleaning trash rack  is designed to separate solid floating trash (foils,polystyrene, wood, etc.) from white water dewatering devices. In the lines processing waste paper the racks are placed after the dewatering drums OBN and they prevent coarse flotates in water pits.

The working part is submerged in a drain between a retention vat OBN and a water pit. Polluted water flows through a moving screen belt where impurities are captured and carried out from the drain. In the top reversal point the trash falls down and the screen is cleaned by a brush. A hopper discharges the trash to a container or to a reject conveyor. The machine runs at the time intervals set according to the line parameters.

Machine design and work safety are in compliance with the EU standards and EAC.
