Paintball Regulator Beer Dispenser

Introduction: Paintball Regulator Beer Dispenser

About: Pub Crawling is an International Drinking Team with a Scenario Paintball problem. Or something like that.

I play for the scenario paintball team Pub Crawling . We have more than 20 members on the team and with a name like Pub Crawling we drink a lot of malted beverages after our games. We travel all over the United States to play paintball and have traveled to Scotland and England for events. In order to keep up our supply of bevarages and meet the demands of the team several members have begun home brewing beer. The nature of our travel schedule also requires that we have a mobile system that is able to utilize available resources wherever the game may be. Because we are a scenario paintball team it makes sense to use as many paintball related parts as possible.

To dispense beer from a keg you need a constant pressure of roughly 12psi. This pressure is far below what most inline regulators can go to so a secondary regulator is needed.

Two Adjustable wrenches
Teflon Tape (more of a supply but whatever, use thread sealant of your choice)

Planet Eclipse Inline High Pressure Reg (free part)
Planet Eclipse OOPS (free part)
ASA adapter (free part)
Generic Air Compressor regulator ($14.99)
1/8" NPT Close nipple ($0.75)
1/8" NPT x 1" Nipple ($1.10)
2x 1/4"x1/8" NPT Bushings ($2.02ea)
1/8" NPT to hose barb (free because I used a male quick disconnect)
Worm Hose clamp ($0.15
Co2 distribution hose ($0.11/foot I also use this for beer dispensing)
Paintball Co2 Tank (free)

Total Cost:  $21.03 not including co2 distribution hose

Step 1: Primary Regulator and Tank Adapter

Co2 pressure can range between 650-1200psi.  Here is the attached On/Off valve, 1/8" NPT x1" Nipple, Primary High Pressure Regulator, ASA and close nipple.  Remember to turn the primary reg down to about 100psi as the Secondary reg has a maximum operating pressure of 150psi.  Beer is dispensed at about 12psi and the Planet Eclipse High Pressure Regulator is a high flow reg which should have no problems feeding this.

Step 2: Secondary Regulator and Hose Connection

Here is the Secondary Regulator.  This is simply an air compressor regulator with an internal bleed off for lowering the pressure when needed.  It is rated between 0-150psi max.    Because Co2 has such a high pressure the primary regulator has to drop the pressure down to a useable psi, otherwise this secondary regulator would blow all of the seals.  Take note that there is a gas in and a gas out side and they are both 1/4" NPT, hence the need for the 1/4"x1/8" NPT bushings.  Also the "Hose Barb" fitting I am using is a paintball quick disconnect fitting.

Step 3: Complete Regulator Assembly

Here is the completed regulator assembly.  The use of the hard piped nipples instead of classic braided co2 line used in paintball means the entire assembly will stay rigid when installed on a co2 tank.  Instead of using the 1/8" NPT nipples you could use braided line.  I personally like the rigid nature of this assembly and the cost of the nipples is minor even though I had plenty of braided line at my disposal.

Step 4: Co2 Gas Line

Here is the Gas Line held on to the "Hose Barb" quick disconnect fitting I used.  There are many different hose barbs available for your co2 line.  You could in theory use a 1/4" to Hose Barb fitting and do away with one bushing completely.  This is just what I had on hand or could find locally and easily.  Whatever size you use here is not critical so long as it does not leak.

Step 5: Completed Assembly With Co2 Tank

Here is the completed assembly with a co2 tank.  After a long day of paintball, either a tournament paintball or 26hr scenario paintball game you are now ready for a nice cold beer.  Usage is simple:

1.  Attach tank to regulator and hose to keg co2 in port.
2.  Back off secondary regulator so that pressure is essentially off.
3.  Turn on OOPS valve to pressurize system.
4.  Slowly increase pressure of the secondary regulator until you are at your desired serving pressure.
5.  Drink beer and enjoy.

    That's cool but does it matter if the brass/other parts are Lead free or not?


    Careful, some paintball CO2 tanks contain oil to lubricate the paintball gun.

    This is actually a misconception with 12gram co2 cartridges which do have minute amounts of oil in them. Bulk filled co2 tanks will have no more oil in them than the normal bulk filled co2 tanks used in home brewing. The Airgas distributor even showed me how their co2 really uses all of the same tanks except for their "Medical Grade" co2.

    I'm talking about the new off-the-shelf ones. If you have them refilled, then no they don't. There will still be oil residue for some time after the first use. Might affect the taste at least.

    While there is really no way to tell what was used in the manufacturing process of paintball tanks that process would be the same as what is used to manufacture the larger tanks used to hold bulk amounts of co2. If there is any foreign substance in the tanks then it will be in there regardless of the tank source. The caveat to this is “Medical Grade” co2, where the tanks are glass lined and cleaned before fills.

    Because this setup passes co2 gas only, not liquid co2, through two regulators and several feet of hose at a low pressure the likelihood of particulates making it through are low. A sintered metal filter could be added inline if someone is concerned about this. Many air compressor regulators have these built in but they can be purchased as stand-alone fittings in various micron sizes. Adding a couple of extra feet of hose in a loop will also help trap anything that is heavier than co2 (which would be just about everything except other gases) before it reaches the keg.

    The real enemy for beer is oxidation from reaction with o2 or other non-inert gases.
