Airflow
Airflow is the movement of air from the inlet across the coil to the mouthpiece. Its volume, direction and speed cool the heater, carry aerosol and determine draw resistance, interacting with power and chamber design.
01
Classification
Airflow describes part of the airflow path – the route incoming air takes from the intake to the mouthpiece. The cross-section, position and adjustability of that route noticeably change draw resistance and aerosol temperature. Because Airflow is closely tied to Bottom airflow, comparing two products is always worth doing across both specifications rather than just one.
02
Practical relevance
Because Airflow controls the ratio of air to aerosol, even a small adjustment changes perceived flavour far more than switching liquid does. Draw style and device choice are therefore closely linked. Looking at Airflow and Top airflow together makes it quicker to tell whether a problem sits in the device, the consumable or the way it is used.
03
Handling it safely
Do not block or widen Airflow beyond the adjustment the manufacturer provides. Blocked openings increase the load on coil and battery, while very wide settings can produce hot aerosol and leaking liquid. Keep the manufacturer documentation for Airflow to hand; in a dispute it is also the decisive basis for warranty questions.

Not to be confused with
Telling Airflow, Bottom airflow and Top airflow apart is easier if you ask which decision each term is supposed to support. Once the three terms are cleanly separated, datasheets and product pages read much faster and lead to fewer mistaken purchases.

Frequently asked questions
- What exactly does Airflow mean?
- Airflow is filed under Parts & technology in this glossary. What matters is not the word's origin but the technical property or rule behind it – and that is always stated on the specific product.
- How do I check Airflow on a specific product?
- On a specific product you will usually find Airflow on the label, in the datasheet or in the manual. If the specification is missing entirely, that is itself a signal.
- What is the difference between Airflow and Air inlet?
- The two overlap but are not identical: Airflow answers a different question from Air inlet. On a specific product both specifications can apply at the same time.
