Arborjet Supersonic Air Knife

The Supersonic Air Knife® line uses high-pressure air to dig trenches, remove compacted soils and locate utilities. Air delivered at twice the speed of sound loosens material without damaging tree roots, irrigation or power lines.

The HF Dielectric has a 36” lightweight Delrin barrel, a brass nozzle and a copper wear tip. Thanks to the dielectric barrel, the device is great for heavy-duty trenching and digging projects where users are working around live electrical sites.
