Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Zeal 4 feels in daily use.
Every serious sourcing conversation about the Zeal 4 eventually arrives at airflow tuning, usually because it is where cost and risk meet.
Where two suppliers look identical on price, airflow tuning is usually the variable that separates them over a full year.

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.
