Can I regulate the speed of a SAT EC or an EC exhaust fan using a standard speed controller?

When installing or upgrading EC fans, questions often arise about which type of speed control can be used. Using the wrong controller may result in malfunction or damage to the fan.

Answer:

No, a SAT EC or other EC exhaust fan cannot be speed-controlled using a standard speed controller. To regulate the speed of an EC fan, a controller designed for 0–10 V control must be used. An example of a suitable controller is Flexit article number 114729. Using the correct controller is necessary to ensure safe and proper operation.
