Efficient fans

Proven efficiency insight, just for the fans.

Understanding the efficiency of commercial and industrial fans—such as roof-mounted, in-line, and wall-mounted units—is an important step toward optimizing fan-system performance. The Fan Energy Index (FEI) provides a better idea of fan efficiency at a specified operation point, helping you understand how it will perform in its intended application.

Getting to know the Fan Energy Index

The FEI ASHRAE 90.1-2019 standard offers clarity during the fan specification process while providing more opportunities to save energy. Check out this quick video from the Air Movement and Control Association International (AMCA) to learn critical issues commercial and industrial air systems face and how the FEI provides insight into addressing them.

Benefits

Quiet operations

The most efficient fans usually operate at the quietest, least disruptive volumes.
Operational excellence

By performing nearer to peak efficiency, efficient fans can reduce stress on system components, extending the life of the equipment and potentially minimizing downtime.
Real-time monitoring

By leveraging new control technology, such as variable frequency drives, efficient fans can assist in real-time monitoring and predictive maintenance efforts.
