The HXX Prodigy vacuum excavator from Vactor Manufacturing is mounted on a 33,000-pound gross vehicle weight Class 7 truck chassis, and has a user-friendly control system identical to the controls used on the full-sized HXX HydroExcavator, and the addition of a standard extendable boom with 320-degree rotation that provides full coverage of the working area. An optional telescopic boom is also available. The mid-sized unit blasts away soil with jets of up to 10 gpm, at rates from 1,500 to 2,500 psi. It has a powerful 16-inch Hg, 3,200 cfm positive displacement blower with a custom-designed and optimized filtration system that can handle both digging mediums – air at 185 cfm and 150 psi, and water at 10 gpm and 2,500 psi, without a bag house. The variable-pressure triplex pump allows the operator to adjust water pressure with the push of a button. It comes with an optional air excavation system. 800/627-3171; www.vactor.com.
