For even more savings in time and product costs, integrate Arch Flex into your wash program. Arch Flex utilizes the spray arch to apply the chosen application to the front of the vehicle, switches on the fly to Flex Pass® Ultra to cover the sides and top surface of the vehicle, then reverts to the spray arch for application to the rear of the vehicle. This application reduces carriage movement and application time by 50%. Arch Flex can be utilized on any low-pressure or high-pressure application that can be applied using the spray arch or Flex Pass Ultra and can start from the entrance or exit for flexibility and time savings.
