VAC 250 and 500 units from Hurco Technologies are a portable solution for potholing and exposing buried utilities. They use a Gardner Denver 14-inch Hg positive displacement vacuum pump and a Giant 4,000 psi, 4.2 gpm high-pressure water pump. The pitched-angle tank eliminates mechanically complicated lift and dump systems for faster and more efficient debris unloading. The 97-gallon water tank sits under the debris tank, balancing the load over the center of the axle, resulting in little change on tongue weight and ensuring a safe towing configuration. All units can be configured to meet specific needs, including auxiliary hydraulics and water heaters. All are powder-coated. 800/888-1436; www.hurcotech.com.
