Freemax Marvos 4: Airflow Tuning for Distributors
Published 2026 · VapeWholesaleHub trade desk
Airflow tuning is the single adjustment that changes how Marvos 4 feels in daily use.
Between the factory gate and the retail shelf, airflow tuning is where most of the value on the Marvos 4 is either created or lost.
Seasonality interacts with airflow tuning more than most forecasts allow for, so a rolling review beats an annual one.
Why airflow tuning matters on the Marvos 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.
