Supersonic Air Knife and Soft Dig Tools
The Supersonic Air Knife is the solution for digging around buried utilities and non-porous material that you want to keep safe during excavation. Shovels, axes and picks can damage fiber optic cables, ducts, pipes and other buried utilities with very little force. The amazing air knife acts as if it were a small charge of dynamite in the soil, but the air traveling at supersonic speeds diverts away from solid objects in the ground. You can even point the air knife at your shoe and it will not hurt your foot.

Supersonic Air Vaccum
The vacuum can use the same compressor as the Air Knife, as long as the compressor size is not less than 100 psi/175 cfm. Nozzles at the inside bottom of the suction tube direct the air stream upward, creating a vacuum at the tube entrance so as to suck crumbled soil, gravel (< 2 3/4 inch), and/or water from the excavation. The materials travel up the tube, and are deposited at/near the end of a 3.5" I.D. or 4" I.D. flexible discharge hose. The diameter and length of the discharge hose are determined by a combination of compressor rating and customer preference.
