Every Airspade Air-Excavation Tool is equipped with a supersonic nozzle, no matter the model. These proprietary nozzles offer lighting-fast air spray that allows users to quickly dig through materials with ease. All AirSpade Arbor Model Supersonic Nozzles are made from an extra-hardened, 416 stainless steel. This tough material prevents any breaking or cracking, protecting not only the airgun, but the user as well. The design of every Supersonic Nozzle allows for a high speed laser like jet which can be used to uncover underground utility lines, pipes, hazardous material containers, or even tree roots without damaging them. On top of having multiple application possibilities, these supersonic nozzles can be mounted on Airspade 2000 Barrels as well as AirSpade Arbor 5000 barrels. Accessibility means less parts to buy, saving time and money. AirSpade boasts over 50 active dealers and distributors spread over North America and a dozen foreign countries thanks to superior performance, user-friendly features, and unequaled customer support. In 2008, the CEG AirSpade product line was acquired by Guardair Corporation. Since then, sales of AirSpade have grown dramatically through the leverage provided by Guardair's sales and marketing clout and increased national and international exposure. Today, countless gas distribution companies and their contractors in North America practice keyhole technology using rotary coring, soft excavation, and core reinstatement. AirSpade has become the industry standard and the tool of choice for thousands of utility and arbor professionals world-wide.
