The Ross and White Model 6×4 HPF-OM Bus Wash System is designed for large transit authorities who must brush wash the maximum amount of vehicles in the minimum amount of time. The system consists of four wrap around brushes and two side brushes mounted on a four column structure with bridge inter-bracing forming the most rigid structure available in the industry. Also included is the high pressure front, lower body, and wheel spray system available on our transit wash systems. As daily weather may dictate different wash conditions, a Human Machine Interface is standard which allows for a custom brush configuration to be selected on a daily basis for maximum throughput. A vehicle wash select pushbutton station is standard, on an individual vehicle basis, to override the wash of the day program for paratransit vehicles or other wash configurations.
