The Ross and White Model TR-1025-HPF-OM truck wash system is designed to wash 13’-6” high trucks on a drive through, high volume basis. The system is a four column two brush wrap around wash system with oscillating overhead mops. A 20 horsepower 90 gallon per minute vertical stainless steel pump provides a high pressure wash to the front of the vehicle at 245PSI. Motorized ball valves switch the flow of the high pressure pump to the wheel areas after the front of the vehicle has passed.
