The Utility Airspade 4000 Series from Guardair Corporation harnesses compressed air to safely uncover burst pipes and underground utility lines without harm. Its supersonic nozzles generate laser-like jets that move at twice the speed. With non-sparking, brass nozzles and electrically insulated, 4-foot fiberglass barrels rated to 300 kV, it maximizes job site safety and minimizes operator fatigue. Its ergonomic handles have full-size plastic-coated grips with openings to accommodate linesmen’s gloves. Dead-man triggers ensure safe operation, and trigger guards prevent accidental activation. It has retractable stabilizer bars and integral pressure gauges. 800/482-7324; www.guardaircorp.com.
