rmedgar, I have been working with a couple members with suggestions for remote aeration. I have been using an AC compressor and DC-AC inverter. Just interested in Keeton's DC compressor to calculate how long it will run. It DOES seem to be high quality for those that can afford it; but the markup must be pretty high. Then again,if they have them on shelf and ready to deliver, it is not a high volume item. Search past threads on "aeration..can I do it myself" and others for more info.
