Model FX50 has been added to the line of vacuum excavators. The unit is powered by a 49-horsepower Deutz D2011L03I engine. It can be customized with a choice of tank sizes, trailer configurations and options. Tank sizes range from 300 to 1,200 gallons, and water tanks from 80 to 500 gallons. The Tuthill blower has a 1,020-cfm capacity, and the water system has a capacity of 3,000 psi and 5-gpm flow. An optional reverse-flow feature enhances the offloading of fluid spoils. The hydraulic tank door opens fully to allow for spoils removal and locks hydraulically.
