Air Bar Zen 4 Airflow Tuning Explained
Published 2026 · VapeWholesaleHub trade desk

Airflow tuning is the single adjustment that changes how Zen 4 feels in daily use.
A range review that ignores airflow tuning will often produce a confident decision and a disappointing quarter on the Zen 4.
Retail staff rarely ask about airflow tuning directly, but their questions almost always lead back to it.
Why airflow tuning matters on the Zen 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Seasonality interacts with airflow tuning more than most forecasts allow for, so a rolling review beats an annual one.
Open airflow serves direct lung users who prioritise vapour volume.
