Lowes now sells a portable CO2 regulator for paintball tanks:
For $90 (plus a paintball tank you have to supply?) you get
regulated CO2 on a 10-foot hose with quick-connect fitting.
Meant for running air tools from your belt, but looks like
it would work fine for beverage applications.
Anyone tried it or looked at it?
Yeah I saw these yesterday at Lowes. The "Rhino Power" tanks(9oz or
20oz) are by Blue Rhino, the same folks that do the propane tank
exchanges. It looks like they are setting up the same system at Lowes
where you return the tank for exchange. However it is so new that no
one at customer service could manage to perform the proper incantation
for the point of sale computer to divulge the actual cost, after the
return credit, of the co2 cylinder. I figured I'd wait a couple weeks
and go ask again.
Here is Blue Rhinos page http://www.bluerhino.com/rhinopower/index.html /
and an alternative to the Kobalt regulator.
One other note: I'd be concerned about using CO2 in my air tools with
the greater cooling effect than air, unknown effect on tool lubrication
and potential for accidentally feeding liquid. The solution is easy
however, just get air fills from a SCUBA shop instead of CO2. It's
cheaper as well.
I'd hope anyone at a SCUBA shop doing fills would understand tank
ratings, particularly if they have purchased the adapters to do
paintball tanks. Of course you could also get a SCUBA tank and regulator
with the appropriate QC adapter and have a nice large regulated air
You can't get much compressed air in a paintball tank, compared to the
expanded volume of CO2.
Depending on the delivery rate, the output CO2 gas should not be that cold.
The tubing coil will warm it very effectively at low delivery rates. The
tank is small enough that ambient heat will warm it directly.
That would be kind of dumb. As well as self limiting.
Read the instructions on the reg.
Misuse it at your own peril.
And wanna bet there is like to be a flow rate fuse or restrictor plate
in the system to limit the CFM draw?
But, it's next to useless. The amount of air you can store at CO2
pressures is very small. CO2 is stored as a liquid. The volume
produced is way higher than air at the same pressure. Just like water
produces way more volume in steam when you boil it.

Hey, why not just fill the tank with water and throw it in a bonfire? Watt
do you say to that? <G>
And it comes at pressures much higher than a paintball CO2 tank is
CO2 at room temperature is in the 850 psi range, though it can get way
higher on an overfilled tank.
Paintball High Pressure Air tankks (HPA) are a whole different kettle
of fish, both in pressure capacity and price as well. Both are much
higher than for CO2 tanks.
HPA tanks will happily take a 4500 psi fill, if you bought the good
ones. CO2 tank burst disks are rated at 3000 psi.
Filling a CO2 tank to it's rated pressure with air would get you about
the same number of shots (nails, staples) as you would get from a CO2
fill without any liguid CO2. Not really worth the effort if you have to
run to the fill station more times than you have to reload the nailer.
By the time the CO2 has travelled through the reg and hoses, (where
the reg limits pressure to 100 psi or so) you can be pretty sure that
liquid CO2 is not an issue. Hoses would blow if the liquid got that far.
At least the ones between the reg and the tool, wher e you can bet they
are not selling you a 3000 psi rated hose to feed a 100 psi rated nailer
So. Air from the Scuba shop is about second in the list of bad ideas,
right after using pure oxygen. :-)
There's actually a product made for beer that uses one of these from
This is more pricey by far, but includes a keg and other stuff. The
regulator (which is basically the main thing you need other than a tank
and assorted hoses) runs around $85.00. I couldn't see what the range
was on the Lowes regulator -- beer is usually dispensed at around 12PSI.
Might even be cheaper to get a bev regulator and DIY your own adapter
(assuming you need one) for a paintball tank, but I don't know.
I think the only other problem is that iirc paintball fills tend to be
expensive for the amount of gas you get.
(Replies: cleanse my address of the Mark of the Beast!)
Also the CO2 gas supply for drinks should not be industrial grade possibly
with oil and other contaminants, the gas should be identified for drink
dispensers and be oil free. I used to buy nitrogen for a film processing
machine, it had to be laboratory grade certified as oil free.
