Does anyone out there know how to filter beer between two kegs. I just ordered the Morebeer keg filter and I wanted to know if anyone has had experience with it or similar filters for their beer? Also if I added the sugar for carbonating can I still filter it between kegs? Thank you and :mug:!
 
The set up just goes between the kegs, and you push with co2.

I'm not sure what you're asking about the priming sugar, though. I'm guessing that you're asking about carbonating the second keg. Depending on the size of the filter you probably can not naturally carbonate after filtering.
 
Filtering is very easy. I suggest you look up the episode on filtering from the Brewing Network.

I'm assuming you got the plate filter kit?.

If so, filtering is pretty easy. I'd recommend hooking up a keg of Starsan and running a bit through first. This will sanitize everything and flush out oxygen. Empty the Starasan from the recieving keg and hook up the beer. Push very slowly into the recieving keg. You will have to manually vent the receiving keg. It will probably take up to 20 or 30 min to filter a while 5 gallon batch.

These plate filters aren't made to withstand pressure, which means you have to filter flat beer. I'm not 100% sure about how effective they are at removing yeast, but I think they do a pretty darn good job. That means you will have a hard time trying to naturally carbonate the filtered beer without pitching more yeast. At that point, you really negate half of the reason to filter. Hope this helps.
 
As long as you use 2 or 5 micron filters, you won't have trouble priming to carbonate. If you use a 0.5 or 0.3 micron filter, you'll have to add some yeast when you prime.
 
I disassemble the whole filter rig and soak it in Starsan. While that is soaking I sanitize the destination keg and purge it with CO2. My filter setup has MFL fittings for the QDs, so after re-assembling the filter and housing, I connect one QD to the purged keg beer out side, and loosen the other QD so I can purge the filter with CO2 using the purged keg beer out. After purging for a bit, I tighten the fitting up, and the rig is ready to go (the purging process also helps to get excess Starsan out of the filter).

I relieve the pressure on both kegs (don't forget to do this!), connect QDs of the filter to both kegs. Then I twist the relief valve on the destination keg so it will stay open. If the valve won't stay open you can unscrew it and take it out. Then I connect my regulator to the source keg set at 0 and turn up the pressure JUST until the beer starts to flow, usually about 2 PSI. It takes about 15 minutes to push all the beer through to the destination keg. Once finished I put the relief valve back on the destination keg, purge just in case there is any O2 in the headspace, and it's good to go.

I don't recommend filtering carbonated beer, as it will foam up a lot. If you use a 5 micron or larger filter, you will get some yeast out along with the proteins that cause chill haze but will leave enough yeast to carb naturally. If you want to sterile filter (1 micron or less) and carb naturally just add some dry yeast to the keg. Any yeast will do, you only need less than a teaspoon to add along with your priming sugar so a single pack of ale yeast will last you awhile if you keep it sealed in the refrigerator.

Great info Sacc. Did you get your whole set up at AHS?
