The drive components shall include fixed-pitch sheaves and multiple V-belts sized for 150 percent of nominal motor horsepower. The supply fan motor shall have a standard T-frame. The entire fan assembly, including drive components, shall be mounted on a common base. The fan base shall be isolated inside the unit. The entire assembly shall be statically and dynamically balanced at the factor to a maximum tolerance of 3 mils peak to peak. FAN MODULATION: The variable volume unit shall operate at design airflow based on fan and motor drive selections. Fan and motor sheaves will be selected for a rpm to develop airflow at design static pressure. INLET GUIDE VANES: Airflow modulation shall be by inlet guide vanes. The inlet vanes, complete with electric actuator, linkage and controller shall be factory-installed and adjusted. The static pressure setpoint shall be adjustable. A duct static pressure sensing probe shall be proved for field-installation. FILTERS: Two-inch medium velocity throwaway filters shall be provided for unit operation.
