The SCREENMASTER CS provides efficient cleaning of a bar screen rack and removal of solids from channel installations. The unit makes solids removal simple with its highly efficient operation. It employs a front clean/front return principle, is easy to install in new or existing channels and, at a 75-degree inclination, has a very small footprint. The design features a simple, continuous rotary motion. It employs rake heads that penetrate the screen slots as they reach the channel bottom and lift accumulated debris up to a discharge height of up to 38 ft (11.6 meters) from the channel bottom.
