Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Zeal 4 feels in daily use.
The Zeal 4 has settled into a stable position in the range, which makes airflow tuning the natural next question for distributors.
Documentation is not paperwork for its own sake; on airflow tuning it is the difference between a clean clearance and a delayed one.
Why airflow tuning matters on the Zeal 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Retail staff rarely ask about airflow tuning directly, but their questions almost always lead back to it.
Open airflow serves direct lung users who prioritise vapour volume.
