The Supersonic Air Knife® line uses high-pressure air to dig trenches, remove compacted soils and locate utilities. By delivering air at nearly twice the speed of sound, it allows the user to loosen even the most compacted soils without damaging tree roots, irrigation, or power lines.

The HF line provides high-flow air excavation with a lightweight aluminum barrel and stainless nozzle. Ideal for heavy duty digging. Additional nozzle assemblies including brass/copper and Delrin® are also available. The liquid injection option uses a standard hose connection for a water inlet which is ideal for injecting water into the work zone and cleaning surfaces.

• Kits come with 1.5″ x 30′ hose with 4-prong Chicago couplings, and travel case.

• The HF line is perfect for users looking for additional digging performance.

• Use with 125 psi/185 cfm compressor.
