Exhaust Fan parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Fan Impeller 1× Backward-curved centrifugal impeller that moves the large air volume the tower needs.
2 Servo Motor 4 parts 1× Brushless motor with an integrated encoder or resolver, driven in closed loop to hold commanded position, speed, or torque precisely.
3 Ball Bearing 2× Deep-groove radial ball bearing.
4 Motor Housing 1× Cast or extruded aluminium shell that carries the stator, locates the bearings, and conducts heat away from an electric motor.
