Published 2026 · VapeWholesaleHub trade desk

Airflow tuning is the single adjustment that changes how Royal 4 feels in daily use.
The Royal 4 has settled into a stable position in the range, which makes airflow tuning the natural next question for distributors.
The most common mistake is optimising for the first order instead of the fourth, which is where Royal 4 economics actually settle.
Why airflow tuning matters on the Royal 4
Restricted airflow suits mouth to lung customers moving from traditional products.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Royal 4.
Open airflow serves direct lung users who prioritise vapour volume.
