Looking to save costs where possible, is there really any use for an air compressor at this scale? I figure we could just buy more C02 and use that for where we would occasionally use compressed air, like the purge between keg washing cycles. The set up is unitanks and kegs, all taproom sales. With that small of unitanks, I doesn't seem like we don't need compressed air for purging C02 before caustic. Is there any other essential use of compressed air that I might be overlooking?

Thanks!
