Vanair Air Excavation Advantages
for Underground Construction
There are times when achieving the goals of an
underground construction project is best achieved
through air excavation. For example, municipal
codes are major considerations regarding the
material removed during the excavation. When
using hydro-excavation, often what you dig out
is not allowed to be dumped back in. You are
required to bring in clean dirt.
However, with air excavation, many times
whatever dry dirt you collect can be reused
for compaction. This is a major advantage in
a remote area where having clean dirt brought
in or to dump 'contaminated' dirt" is prohibitive
because of the distance. Also, the issues of local
water availability, water restrictions, and electrical
lines when using hydroexcavation are not a
problem with air excavation.
While water can dig faster because it is denser
than air, the time difference using air excavation
can be resolved using higher-pressure air
excavation. Because air excavation can continue
uninterrupted for bigger jobs and is not restricted
by the availability of water or the removal of
contaminated dirt, productivity and efficiency
are actually increased.
Additionally, air excavation provides clean,
dry digging when potholing. This advantage allows
you to reuse the dry spoils for re-compaction,
increasing your productivity, and decreasing
your operating costs. Air is nonconductive with
underground utilities and eliminates the muddy
spoils of hydro excavation.
To help accomplish jobsite objectives and
minimize downtime, air excavation retrofit
systems for older hydro-excavators are available.
These underdeck systems provide air power
without claiming space above the truck frame
or using the hitch. Many construction crews find
dual pressure systems are useful in situations
necessitating jackhammer use or breaking up
frozen ground before air excavation .
Vanair®'s air compressor kits provide you with
flexibility in the field to get the job done effectively

and efficiently, no matter the soil type. Vanair®'s
durable, field-proven, space-saving systems are
engineered and manufactured in the USA with
