huffing? air from still?

Strangest thing do you get air movement through a still. I am doing the cleaning run on my pc but I can feel air like huffing out pc. Not a steady stream but huffing
Collection rate and volume percentage etc all normal. Pc is cold to touch for full length from water output down. There is zero smell and it does not fog a mirror. But I can feel air movement.. is this just huffing? Cant say I ever noticed this before.. :-B

The air has to expand with temp. Might just be that.

I get it a fair bit with the thumper but I imagine there is some surge caused by the bubbles in there.
