A quick question on "huffing"

When I built my new liebig I read pretty much every forum post on the topic, and it works great. I only get (what I thought was) huffing when I turn the boiler all the way up and turn the cooling way down; so yay for me. I had though that huffing was the little "puffs" of visible vapor that periodically come out the end, lost ethanol.

However I noticed on my last run that there is also a small, constant air pressure coming out of the condenser. It's a very slight amount, I only noticed it when I had my wet finger near the output. The air is cold in temperature, so I don't think that it's lost ethanol, but I just wanted to confirm with the more experienced folk that this is normal behaviour.

Most liebigs huff at least a lil bit.

This can cause a some splattering while collecting and an aggravating hydrolic affect while using a parrot.

Vapor loss is another issue.

Thanks, I've actually read that all the way through a few times already. My condenser takes those things into account (the cooling supply, the scrubber, etc). I know that the "puffs" can be normal, and I have done several runs without the "puffs".

My question is related to the constant flow of air that comes out, is that "vapor loss"?
