The WW960s PECO Wheel Washer is designed to remove brake dust off the wheels of vehicles. The 96” brush rotates parallel to the vehicle tires, continuously scrubbing the wheel as it turns. The brush has a unique stepped design that insures safe and thorough cleaning of the whole wheel. Standard on the WW960 is the Retract System which allows the brush to be retracted away from the vehicle until the wheels are in position. Once the vehicle reaches the brush, the brush will extend in to meet the wheel. The cylinders allow a constant brush pressure against the wheel and will retract the brushes once the vehicle leaves the brush assembly.
