AirSpade, a division of Guardair Corporation, is offering International Construction and Utility Equipment Exposition (ICUEE)  attendees a 10% discount and free ground shipping. From now until Oct.15, 2015, attendees can enter the code ICUEE2015 to receive the discount.

The Utility AirSpade uses compressed air to quickly and efficiently excavate soil covering sensitive underground objects without damage. Featuring a patented supersonic nozzle that generates airflow of Mach 2, the Utility AirSpade fractures and dislodges the soil, but leaves tree roots, cables, and metal and plastic pipes unharmed.
