| "With the entire paintball industry gradually separating
itself from using CO2 in exchange for high pressure air, many questions
are abound. From the simplest questions to the slightly more complex,
the following is intended to shed some clarification on high pressure
air. The advantages of high pressure air over CO2 are numerous and
well known, so those items will not be included in this summary.
Let me start by say that high pressure air is nothing
new. Having seen hydrotests dating back to 1919 at 1,800 psi, the
process of compressing air at higher than normal pressures is older
than most of you reading this. The only changes since these early
times are still higher pressures pumped through lighter and more
efficient compressors with purification systems that purify air
to beyond breathing air standards.
There are many applications of high pressure air, many of which
go by unnoticed in many industrial applications. The most prominent
role for high pressure air has centered around breathing air, namely
for firefighters and scuba divers. Over the past few years, another
application for this same air has emerged, paintball. The only difference
between the air used by firefighters/scuba divers and the air used
by paintballers is that the air for firefighters/scuba divers must
be purified to breathing air standards. This is not to say that
air for paintball use need not be purified. This air must still
be cleansed of all oil, particulates, and most moisture so that
it is not passed into the paintball air system and clog up the regulator.
Many people within paintball confuse high pressure air with nitrogen
and rightly so. For the end use of shooting paintballs, they are
interchangeable. The only difference between high pressure air and
nitrogen is mainly how they are derived and how one would actually
refill a paintball air system.
Currently, shops and fields have only a few viable options for
refilling paintball air systems. The first option one has is scuba
fill stations. This method consists of buying a few scuba cylinders
and a scuba fill station, then refilling the paintball air systems
from the scuba tank. This method is generally the cheapest way to
go, but also the most limiting. With standard scuba cylinders, the
maximum pressure is 3,500 psi, so you will never be able to fill
over 3,500 psi. In addition, with scuba cylinders being so small
you will only be getting a few fills before you drop below 3,000
psi and get only marginal fills after that point. Then it is back
to the local dive shop to pay for more fills.
The second option for refilling paintball air systems incorporates
the use of a booster. What is done in this situation is you purchase
a booster (approx. $2,000) typically made by Teledyne, coupled with
air or nitrogen purchased at a local welding or gas supply house.
You connect your rented (or purchased) storage cylinders to a your
booster, then connect to the paintball air system. Some gas supply
houses carry nitrogen while others carry compressed air (this is
where the two gasses become interchangeable). If you are able to
get 4,500 psi gas from your supplier, you can start filling paintball
air systems. Once the air in your rented storage bottle gets below
your desired pressure, you then turn on the booster and boost the
air to your desired pressure. This option is good for low volume
refilling and is cheaper (in the short term) than compressing your
own air. Negative aspects of boosting air are that (1) you will
always need to rent or purchase gas from a supply house which can
get extremely costly over the long run, (2) booster systems are
not intended for high volume and (3) boosters consume a large amount
of gas (boosters use low pressure air to drive themselves).
The final option that I will discuss is our preferred method, and
that is utilizing a compressor. Most newer compressors from manufacturers
such as Bauer are rated at 5000 psi, so the need for a booster is
eliminated. Typical installations with an air compressor include
the compressor, some storage cylinders, and a fill station. The
compressor takes the ambient air and compresses it through multi-stages
to your desired pressure. From the compressor, the compressed air
is usually stored in a few storage cylinders (also known as a ‘Cascade
System’) and then into your fill station. While the biggest
deterrence for people from an air compressor is the startup cost,
the long term costs of a compressor are lower because you do not
need to continuously buy or rent gas cylinders as you would with
a booster. With a compressor based system, you are completely self
sufficient.
While this summary is by no means comprehensive, I hope that it
cleared up some of the more basic questions. If you still have questions
