Large Structures, Forced Ventilation
In large structures equipped with forced ventilation, the first fan row should be within a few feet of the intake end. The first fan should be:
- centered along the end wall OR
- placed no more than 25' from the side wall, with additional fans in the row equally spaced no farther than 50' apart.
Lengthwise, fans should be equally spaced no farther than 70' apart. All fans should be equipped with oscillation, sweeping 180° in the direction of airflow.
