Using high-volume compressed air, the Supersonic Air Knife is able to loosen and remove soil from an object buried in the ground without risk of damage to that object. The air knife does it faster and more safely than digging with a shovel.
Air exits the tool at MACH 1.7 which causes the soil to fracture. This creates a momentary cavity in the ground. As the soil continues to fracture, the air loses velocity and escapes through the now loosened soil. Any solid objects in the path of the air stream remain undamaged.
Soil can be removed from the excavation site in two ways. For shallow depths, the Supersonic Air Knife is able to blow the material away from the hole. However for deep holes, the companion Supersonic Air Vacuum can remove the loosened soil from the hole.
Both, the X-LTL and the X-HFL introduce low-pressure liquid into the air stream of the air knife. The liquid is carried along as a fine mist, penetrating with the air into the fractured soil. This process allows for a more even and efficient distribution of applied liquids through the target area, as well as aiding in decompacting the soil.
