Air-spade 4000 series
Air-spade 2000 series
The patented supersonic nozzle in the Air-Spade® turns compressed air into a high speed, laser-like jet moving at twice the speed of sound; Mach 2. All of the energy and momentum of this air moving at approximately 1200 mph is focused onto the soil, dislodging it in a fraction of a second. The aggregate nature of soil aids the ability of the air to fracture it; while stronger materials and ones that are not porous like metal or plastic pipes, cables, or even wooden tree roots are unaffected.
Because of its unique, focused air-jet, the Air-Spade works in most soils, even hard clays. The Air-Spade will dislodge up to several inches deep in a medium to stiff soil. Unless the soil is highly compacted, dwelling on the same spot is unnecessary and tends to increase spray.
The Air-Spade can be moved over the soil surface at a rate of about 1 to 2 feet per second. When several inches of soil have been loosened, the soil should be removed to expose a fresh working face for the air jet. Vacuum suction, as provided by our AIR-VAC unit, is an excellent companion to the Air-Spade since it is likewise non-damaging.
