Air Bar Nex 4 Airflow Tuning
Published 2026 · VapeWholesaleHub trade desk

Airflow tuning is the single adjustment that changes how Nex 4 feels in daily use.
Between the factory gate and the retail shelf, airflow tuning is where most of the value on the Nex 4 is either created or lost.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Nex 4.
Why airflow tuning matters on the Nex 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Documentation is not paperwork for its own sake; on airflow tuning it is the difference between a clean clearance and a delayed one.
Open airflow serves direct lung users who prioritise vapour volume.
