Insight

The robustness of the Passavant^® Climber Screen and its easy maintenance are due to the lack of ropes or chains for driving the rake. No moving parts are submerged in the wastewater. The steady sense of rotation of the drive motor protects the driving parts. The cleaner carriage can be stopped in any position thus allowing maintenance work on the operation floor without the need for a maintenance platform. The screen is equipped with an electromechanical overload protection system. As well a simple machine cover or a complete encasement is possible.

Efficient and reliable cleaning

The Passavant^® Climber Screen ensures efficient and reliable cleaning of the bar rack. The maintenance-free pin rack drive guarantees absolute synchronism and quiet running of the rake. The cleaner carriage is driven by a pair of cogwheels around a pin rack. The rake is steered by rollers running in a guide rail and a follower track. The rake performs a looping type movement as the cleaner carriage ascends and descends. Jamming and imprecise meshing of the comb plate is hence eliminated, vitally important to the cleaning efficiency with a small bar spacing. The defined meshing of the rake due to its own weight is intensified by the motor force improving the cleaning efficiency.
