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
