GENERAL INFORMATION
GUARDAIR CORPORATION’S AIR-SPADE Series 2000 is a compressed air-powered tool
used for excavation of a wide variety of soils. AIR-SPADE Series 2000 consists of an
ergonomic pistol grip style handle, an insulated fiberglass barrel, and a patented
supersonic nozzle. Typically powered by a portable tow-behind air compressor, the
AIR-SPADE Series 2000 provides a safe, powerful and efficient method of uncovering
underground electric lines, pipes, and tree roots without harm. Capable of excavation
where a shovel or backhoe cannot be used, AIR-SPADE can be equipped with multiple
nozzle sizes and a variety of extension lengths for optimum job performance.
The heart of the AIR-SPADE is the patented supersonic nozzle which produces a focused
“laser-like” jet of air moving at approximately 1,200 mph (1,900 km/hr), or nearly twice
the speed of sound. This supersonic air-jet penetrates voids in the soil and expands
rapidly, therefore fracturing the soil. Unlike the hard cutting edges of shovels, picks,
blades, or buckets, the air-jet is harmless to non-porous items such as tree roots,
buried pipes, or cables. Excavating with AIR-SPADE is much easier and many times
faster than hand excavation.
The AIR-SPADE supersonic air-jet outperforms “homemade tools” featuring a pipe
nipple or a crimped orifice. Air flow from these tools expands to atmosphere in an
unfocused, complex manner while the supersonic air jet delivers significantly more
kinetic energy and more focused momentum. In practical terms the AIR-SPADE does
more work by moving more material, and harder material, in a shorter period of time.
