The air gets purged as the potstill system (cap, riser &/or lynearm &
condenser) gets filled with assorted vapors from the boil. Some of
that moisture-laden air will obviously strike the cooling surfaces
and condense. Taste the drips. You'll find it tastes like a copper
penny, not like alcohol.
As for your worries about laminar flow, yes you could improve your
shotgun's performance by adding LOOSELY teased mesh inside the 13mm
tubes. However as it's fitted to a potstill, you better not have
a 'puke', or you may block the whole shebang.
