Variable Frequency Drives allows for you to control the airflow through your system by changing the fan speed without breaking the bank.  Without VFDs, one has to manually open or close dampers, creating high manual labor cost. Furthermore, if there are multiple dampers on the system, then tampering with the opening and closing of any one damper, can cause the airflow balance to be off and can increase the static pressure of the system.  

The VFD allows you to control the airflow of the fan, rather than allowing a constant high air output, as would be the case when dampers are being used. VFDs give the system the airflow that is required while lowering electrical costs.  VFDs can further lower costs by replacing motor starter control panels. All in all, using a VFD is the smart way to control your airflow.
