Airflow management systems and methods for filtered air systems

Abstract

Systems and methods for controlling operation of one or more fans of an air handling system having one or more filters or filter banks. A current air volume at an inlet side of the fan(s) is determined. In some embodiments, the inlet side air volume is determined via sensed pressure at the inlet side (e.g., pressure transducer open to a flow station at the inlet side). A controller operates to control or regulate a speed of the fan in a manner that maintains a constant air volume through the air handling system, for example based upon a comparison of the current air volume at the fan with a target air volume.
