Featured exclusively on AirSpade air-excavation tools!AirSpade?s patented design turns compressed air into a high-speed, laser-like jet. This jet moves at Mach 2 — twice the speed of sound! These supersonic nozzles deliver superior performance. This nozzle outputs an air flow of 105 cubic feet per minute (CFM).These nozzles provide much faster and more efficient excavation than standard methods. Use them to uncover buried utility lines, pipes, or even sensitive tree roots without causing damage! Mounts on the standard AirSpade 2000 Series barrel.
