Published 2026 · VapeWholesaleHub trade desk

Airflow tuning is the single adjustment that changes how Ultra 4 feels in daily use.

Consistency across batches matters more than peak performance for Ultra 4, and airflow tuning is where inconsistency first appears.

Why airflow tuning matters on the Ultra 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 Ultra 4.

Open airflow serves direct lung users who prioritise vapour volume.
