GENERAL INFORMATION
GUARDAIR CORPORATION’S UTILITY AIRSPADE is a compressed air-powered tool
used for excavation of a wide variety of soils. UTILITY AIRSPADE features an ergonomic
pistol grip style handle, an insulated fiberglass barrel, and the patented AIRSPADE
supersonic nozzle. Typically powered by a portable tow-behind air compressor, the
UTILITY AIRSPADE 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, the UTILITY AIRSPADE can be outfitted with
multiple nozzle sizes and a variety of extension lengths for optimum job performance.
The heart of the UTILITY AIRSPADE is the patented AIRSPADE 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 buried pipes, cables, or even tree roots. Excavating with UTILITY AIRSPADE is much
easier and many times faster than hand excavation.
The UTILITY AIRSPADE outperforms “homemade tools” featuring a pipe nipple or a crimped
orifice functioning as the “nozzle.” Air flow from these tools expands to the atmosphere
in an unfocused, complex manner while the supersonic air jet delivers significantly more
kinetic energy and more focused momentum. In practical terms, the UTILITY AIRSPADE
does more work by moving more material, harder material, in a shorter period of time.
