The Supersonic Air Knife line of handheld tools uses high pressure air to dig trenches, remove compacted soils and locate utilities. Their unique MACH 1.7 air speed allows the removal of even the most compacted soils without damaging tree roots, irrigation, or power lines. The product is also used in rescues where soils may have collapsed, and the use of construction equipment may cause injury.
The Supersonic Air Knife tools are used by service providers worldwide for:
- Arboriculture, landscape, and irrigation
- Utility, construction, and rescue
- Environmental remediation, de-mining, potholing and keyholing
They are ideal for installing or repairing irrigation lines or for sensitive arborist work including, vertical mulching, bare rooting, radial trenching, and soil aeration. They may also be used to safely uncover buried electrical, gas, communication, or water lines without the risk of damaging the target.
Supersonic Air Knife digging tools are complemented by high-powered air vacuum tools, which utilize the same compressor and are used to remove debris loosened by the Air Knife through a large discharge hose.
Additional hoses and product accessories such as a variable nozzle and traveling case are also available. See all accessories.
LT Standard (400-11), LT Short (400-21), LT Split (400-41)
Lighter weight Air Knife with standard length barrel. The barrel is made from aircraft aluminum and has a stainless-steel nozzle and wear tip. Ideal for Arborists, Landscapers, and trenching for irrigation and light construction. The aluminum barrel comes in two lengths-45.75” and 41”. A split barrel is also available for the travel case option.
LT Liquid (401-00)
Standard lightweight Air Knife with liquid injection capability. This device uses a standard hose connection for injecting liquid into the work zone and cleaning surfaces.
