A portable method of dispensing your kegs on the go. No longer do you have to lug around your heavy, unbalanced CO2 tank. This hand held CO2 unit pushes out your beer using small 16 gram CO2 cartridges, KEG955. This unit works with ball lock kegs. Uses 2-5 16g cartridges to push 5 gallons of beer. It will not work for carbonating your beer because of the small amount of CO2 in each cartridge.,,Caution the cartridges contain liquid co2 that will dispense at over 600PSI. With that in mind, we suggest having the faucet open before pushing more co2 into the keg. Also, do not push the inject lever when not hooked up to a keg as you will put over 600PSI into the quick disconnect and will blow the top threads off.
