Published 2026 · VapeWholesaleHub trade desk

Airflow tuning is the single adjustment that changes how Nex 4 feels in daily use.
Buyers who treat airflow tuning as a commercial discipline rather than an afterthought tend to hold margin for longer.
Consistency across batches matters more than peak performance for Nex 4, and airflow tuning is where inconsistency first appears.
Why airflow tuning matters on the Nex 4
Restricted airflow suits mouth to lung customers moving from traditional products.
Keeping a short internal note on airflow tuning for each SKU pays for itself the first time a dispute arises over the Nex 4.
Open airflow serves direct lung users who prioritise vapour volume.
