The HXX HydroExcavator from Vactor Manufacturing comes with a Robuschi blower option that’s rated for 6,176 cfm and 28 inches Hg. It has a 3,000 psi variable water multi-flow pump with DigRight technology that allows the operator to select a maximum water pressure limit to prevent the pressure from exceeding site or industry requirements. The technology includes a user-selectable maximum water pressure setting that controls the water pump’s maximum water pressure output, preventing wear and tear on check valves, unloader valves and relief valves by avoiding bypassing water. The system has three default selectable pressure limitations based on industry best practices for digging around underground utilities – 1,500, 2,500 and 3,000 psi – with the option to deactivate the feature. 800/627-3171; www.vactor.com.
