X13 MULTI-SPEED/TORQUE MOTOR
Table AO — Pulley Adjustment (Fan RPM at motor pulley settings)
* Humidi-MiZer models only
General Fan Performance Notes:
1. Interpolation is permissible. Do not extrapolate.
2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static pressure
caused by any FIOPs or accessories.
3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories can add
static pressure losses.
4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would work,
Carrier recommends the lower horsepower option.
