The Aeolus takes in air from the top.
-- oh I don't have one so I'm talking from pictures.
the air goes down to the chamber then goes up to the drip tip.

Hadn't heard of that one before.

What I do have and am vaping is a manta topcap (I actually have it on my aris):
the manta topcap actually has holes going down through the metal THEN down the SIDES, THEN come out horizontally onto the coil
