Definition

The commanded speed of the fan that moves process or exhaust air.

Why it matters

This setting changes the roasting environment and therefore the shape and repeatability of the profile.

How it is measured or recognized

Record the machine’s defined unit together with batch size and the other active controls.

Roasting tip

A percentage or step is machine-specific; make deliberate changes and learn the response lag of your roaster.
