Airflow Tuning Guide for Air Bar Zen 4

Published 2026 · VapeWholesaleHub trade desk

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

Between the factory gate and the retail shelf, airflow tuning is where most of the value on the Zen 4 is either created or lost.

The most common mistake is optimising for the first order instead of the fourth, which is where Zen 4 economics actually settle.

Why airflow tuning matters on the Zen 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.

Commercial terms

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

Currency movement over a ninety day cycle can outweigh the difference between two competing quotations.

Carton (92 units)	Tier 1	7-12 days
Pallet (1212 units)	Tier 2	7-12 days

All figures above are indicative working ranges used for planning. Final specification and commercial terms are confirmed in writing before any deposit.

Frequently asked questions
