Fixin' to start doing full boil batches and been reading into the importance of getting 02 in to the wort prior to pitching. Got an idea. After the boil is over, or after chilling or at some point (not sure exactly when at this point as it is an idea), connect your air compressor hose right on to the barb end of the spigot on the keggle. Build up pressure and then slowly crack open the shut off valve and let the air pressure push air back up through the drain pipe into the wort. I mean, it isn't pure 02 and more or less the easier equivalent of using a fish tank air pump, but would that work??? Maybe the bubbles won't be fine enough.

No dice pal, the air in a compressor is pretty nasty stuff. You're also right about the bubbles being too large. If you run it through a hepa filter though, and put a diffusor stone on it, it just might work.

I use my ferret to airerate it.

I get her all would up and toss into chilled wort.

It also gives my beer that little something extra for flavor.

If you get enough turbulence, big bubbles should be effective as well. However that sort of thing may blow a hole right through the filter. I wouldn't want the air in my compressor entering any kind of food product without an oil separator and REALLY GOOD outlet filter.

I pitch yeast, cover end of prim fermentor and shake a few times. Yeast just takes right off.

It would take so many dollars worth of equipment to make the air coming out of that thing clean that you might as well buy an oxygen tank and an aeration stone.

I love my wort wizard, Dude posted a DIY one a while back.

That's exactly how I do it when I don't get enough aeration when I pour it from the (chilled) wort tun.

Many of the newer compressors are "oil less". The don't even have a crankcase to put oil into. It's just the piston with a teflon 'ring' on it. No more hazard than an aquarium pump.

But those aren't high output, 60+ gallon, 5+ hp, two-stage monsters. Anything less doesn't go into my shop.

I still wouldn't inject shop air into my wort...even if I had an oil-less compressor. Splashing and shaking works, a $20 new aquarium pump seems simple, and BernzOMatic's small O2 tanks/regulators aren't much more expensive...
