Airflow System parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Draft Fan 1× Draws hot gas through the drum and sets the airflow that drives heat transfer.
2 Airflow Damper 2× roast and cooling dampers
3 Exhaust Duct 1× Carries spent gas and chaff toward the cyclone and afterburner.
4 Fan Motor 1× Drives the draft fan impeller.
5 Stator Assembly 3 parts 1× Stationary part of an electric motor: a slotted laminated core wound with copper coils that produce the rotating magnetic field.
6 Rotor Assembly 4 parts 1× Rotating member of an electric motor: a laminated steel core carrying permanent magnets or conductor bars, pressed onto a shaft that delivers the torque.
7 Ball Bearing 2× Deep-groove radial ball bearing.
8 Temperature Thermocouple 3× bean, air, exhaust
