Consider installing a VFD controller or other form of variable speed motor control. Control of the variable speed motor and damper position are very important to ensure proper ventilation therefore consultation is suggested when deciding about purchasing a VFD or variable speed motor. Average energy savings have been reported at 52% by installing a VFD on commercial HVAC motors.

Notched belts run cooler, have longer durability, and run with an efficiency of ~97% compared to a peak of 95% for V-belts. Synchronous belts operate at ~98% efficiency over a wider load range, need minimal maintenance and can operate in wet/oily environments. However, they transfer more vibrations, are sometimes noisier than V-belts and less suited for shock-load applications.

If it is possible to lower the fan speed, substantial reductions in power consumption are possible. Fan power consumption has nearly a cubed relationship to fan speed. For example, reducing the fan speed by 5% equates to almost 15% reduction in fan power. The entire system needs to be analyzed to ensure that no adverse effects occur to airflow and ventilation, before attempting to lower fan speed.
