    Hi folks,

    Not sure if anyone has or uses this system but I thought I would share a simple system I have developed to refill these kegs.

    I live in France and the kegs for this system are quite easy to come by. The system is described in this thread over on brassageamateur.com. It's in French but Google translate should do the job.

    Basically, these kegs have a foil bag that contains the carbonated beer. The system pumps air into the void between the keg itself and the bag to push the beer out. The system for refilling these thus involves, simply sucking the air back out with the beer outlet connected to whatever you want to suck back in. As the air is removed from between the keg and the bag, beer will be sucked in through the hose.

    The first thing you need is a simple air suction pump. There is a nice description of how to put this together here (again in French). I just used this 12V pump from Amazon.co.uk. You can also find it elsewhere and goes by various names/codes including AIRPO D2028B and ROB-10398.

    Then, you need to connect it to your empty keg. I improvised a solution for this using:
    - a 5 x 7 mm silicon hose
    - a 12 x 18mm silicon hose
    - a coupler for joining two 5 x 7 mm hoses.
    - two 12mm>6mm barbed straight hose coupler/reducers like here

    So, the system works as follows:
    - A 12mm > 6mm barbed coupler connects the 12 x 18mm silicon hose to a section of 5 x 7mm hose which in turn connects to the pump
    - The other end of the 12 x 18mm silicon hose connects to the air connection of the perfect draft keg adapter
    - However, we need some way to depress the air valve inside the keg adapter air connection
    - To do this, we use the second 12mm > 6mm barbed coupler which goes inside the 12 x 18mm silicon hose. The idea is that the narrow end of this will push in the air valve on the air connection of the keg adapter
    - However, we need air to pass through this, so we drill a few holes in it with a small bit (2 or 3mm)
    - Finally, the small opening of the 12mm > 6mm barbed coupler is a little too wide to depress the airvalve, so with the help of a lighter flame, we gently heat the end for a second or two, and narrow the opening when the plastic is soft.

    Hey presto. Some images of the system:

    Hi thanks for the information you have shared. I have recently purchased a perfect draft machine and am keen to refill the kegs. My diy skills are not great!! Can you clarify how I would connect the adaptor to a an external vessel containing beer? I am planning to purchase a home brew kit and then transfer beer to kegs in batches. How many times can the kegs be refilled? Any further photos would greatly appreciated thanks again for sharing your knowledge.

    They look great, especially for transporting smaller amounts of "bright" beer out of the house.

    But one word of warning ... You appear to be using silicon tubing for beer line. The beer in the line will oxidise (or turn acetic) if left for more than a day or two. I learnt silicon tubing is very permeable to oxygen the hard way (yeuch!). Change it to something more suitable before you learn the hard way.

    Hi folks. Thanks for the interest.

    Regarding filling your kegs - if you look at the picture I attached, there is a 5/7mm silicon hose leading to a blue bowl. You would just lead this hose to your FV and the beer would be drawn in through the tube (even from a height) whenever you turn on the pump (which you would use in bursts).

    Regarding infection, over on the French forums I linked, they did 3 fill/empty cycles with water and suitable sterilizing agent and that seemed to work well.

    Regarding silicon tubing - this is only needed when filling / sterilising the kegs, so nothing should be exposed for any length of time.

    Thanks sorry for what might seem like an obvious question but what is the process for sterilizing the keg, I can see from the photo as to how it can be refilled but how do you then empty the keg if you are cleaning it before refilling with beer?

    So over on the French forums I linked - they do 3 fill/empty cycles with sterilizing solution. To empty the keg you just need to pump air back into the void which just means connecting to the other hose connection on the pump
