Air Bar Diamond 4 Airflow Tuning for Bulk Buyers
Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Diamond 4 feels in daily use.
Buyers who treat airflow tuning as a commercial discipline rather than an afterthought tend to hold margin for longer.
Where two suppliers look identical on price, airflow tuning is usually the variable that separates them over a full year.
Why airflow tuning matters on the Diamond 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.
