10.3 Blower Drive System—Forward-curved Blowers
Periodic checks of the blower package include the belt, motor mounts, fan bearings and impellers.
The units are manufactured with factory-supplied, adjustable motor sheaves. Due to variations in application, you may want
to substitute a fixed motor pulley for the adjustable sheave after you obtain and confirm the desired air flow. This
substitution reduces vibration and wear on the belts and pulleys. Consult your Vertiv sales representative for more
information.
