Clogging at the coil mostly happens when the intake holes absorb too much oil, but the heating element doesn’t atomize them enough (Or because of the heating area). It clogs on the airflow holes when the oils cooled down
So I think we either get a Pre-heating battery or make the intake oil sizes smaller. So the oil in the coils can be atomized fully.
I don’t intend to ad some posts here, but our BBMesh ceramic coil had a large heating area, and can heat up the oils more evenly on the heating surface.
