Vac-Con combination machines are available in configurations from 3.5- to 16-cubic-yard capacities, with hydrostatically driven two- and three-stage centrifugal compressors or several optional positive displacement blowers with up to 27 inches Hg. High-pressure, smooth-flow water systems are offered up to 120 gpm and 3,000 psi, with cross-linked polyethylene water storage tanks with total capacities up to 1,500 gallons to handle the cleaning of small- or large-diameter pipe. These machines can be equipped with a 180-degree articulating front-mounted hose reel in capacities up to 1,000 feet, and high-pressure hose diameters from 5/8 to 1 1/4 inches. There are front-mounted telescopic booms available with up to 10-foot extensions, and 8- and 10-inch tube diameter. It can double as a vacuum excavator with the optional hydroexcavation package. This allows the operator to reduce the volume of water, maintain the pressure for digging and direct the flow through a conventional excavation hand wand. 904/284-4200; www.vac-con.com.
