I've been reading a lot about aeration. I bought a disposable o2 tank from lowes but started having trouble finding a good regulator. There was one on ebay that sells and ships for$15 total, but wasn't sure if it was compatible. Plus I read a lot of people said the tanks didn't last long at all. So I thought I might go the route of a air bubbler with sanitizing filter. I already have a large air compressor, maybe I can keep the PSI low and use it, then all I would need would be a 2 micron or .5 micron stone and the 1/4" tubing, and off course the filter disc. I have read a couple of post about using a filter that would catch oil from the compressor. Can anyone give a definite answer on how to make this system work. I have a craftsman 1.6 HP, 160 psi max, 26gal compressor. cheers and thanks in advance.

I have rigged up inline aeration with a compressor using a ss airstone.

The compressor I use is a basic oilless harbor freight model:

I also added a desiccant filter:

The regulator on the compressor can go low, but the stock gauge does not register below about 15 psi. I added a 0-15 pressure gauge to accurately dial in the 5 psi I wanted, but you could probably go by feel if you were aerating in a carboy.

Before the air goes into the stone it travels through one of these filters:

So far so good. Been using it a year and beats O2 tanks for my system. YMMV.

I use the tanks from lowes/homedepot. I get about 7 batches *ten gallon) from one tank.

I've been using compressed air to aerate <= 1.070 wort. Works great. Pure oxygen is necessary > 1.070.

If you have an oiled compressor, you'll want to use a borosilicate oil/gas separator. Mcmaster sells them for less than $10.

The temp you chill your wort to before is very much just as important. I just whip it with a spoon and I don't have any fermentation problems. Technically dry yeast does not need any aeration.

I use Harbor Freights Air Brush Compressor. They are very clean air, small light. Works with .2 micron stone, and a .05 micron filter in line(from surgical supplies). Needle valve controls flow. Does a great job, around $50 or so.

Really, so far I've gotten around 30 ten gallon batches from one disposable oxygen cannister. One of us is doing something wrong.

thanks for everyones input....I bought a disposable oxygen tank from lowes and was trying to find a valve to release the o2, but I got frustrated with the prices of them and couldn't find a cheaper alternative, plus I have to keep buying the tanks. so I bought the the air pump and stone kit from NB. I will probably get the o2 system going eventually for when I start making IIPAs.

nothing personal but i wouldn't use a regular air compressor for this at all. I have an 80 gallon to run my air tools and fill tires and such. no way would i use it to aerate beer. filtered or not. just too risky in my opinion

Totaly agree on the garage compressor NOT being used. Thought about it, then I drained the tank and was reminded of the condition of the tank, no tanks!
