Setting a new standard for air excavation tools, the Utility AirSpade 4000 Series harnesses the power of compressed air to safely uncover underground utility lines without harm. AirSpade's high-performance, proprietary Supersonic Nozzle generates a laser-like jet that moves at twice the speed of sound for faster, more effective digging. With non-sparking bronze nozzle, brass components, electrically insulated 4 ft. barrel rated to 300kV, and a lightweight, ergonomic handle, the Utility AirSpade 4000 maximizes jobsite safety while minimizing operator fatigue. Aluminum handle features full size grip opening to accommodate linesman's gloves. Dead-man trigger ensures safe operation and trigger guard prevents accidental activation. Retractable handle provides superior operator control. Integral pressure gauge ensures optimal digging performance. Made in USA.
