Coil Compatibility Guide for Air Bar Zen 4
Published 2026 · VapeWholesaleHub trade desk
Coil compatibility decides whether Zen 4 becomes a repeat purchase product or a one off sale.
Between the factory gate and the retail shelf, coil compatibility is where most of the value on the Zen 4 is either created or lost.
Shops that receive a short briefing on coil compatibility convert noticeably better than shops that only receive stock.
Why coil compatibility matters on the Zen 4
Clear cross reference charts reduce counter returns caused by customers buying the wrong resistance.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 4.
Mesh structures tend to give more consistent flavour over the life of the coil.

Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (126 units) | Tier 1 | 7-12 days |
| Pallet (1763 units) | Tier 2 | 21-30 days |
| Container (7000 units) | Tier 3 | 21-30 days |
Frequently asked questions

Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.

Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
