Can I regulate a central exhaust fan motor using a standard speed controller?
When installing or retrofitting a central exhaust system, it is important to use the correct type of speed control. Many people wonder whether a standard speed controller can be used, or if a dedicated solution is required to ensure stable and quiet operation.
Answer:
No, Flexit does not recommend regulating a central exhaust fan motor using a standard speed controller. Such a solution may cause humming noise in the motor and result in undesirable operation. For correct and stable control, it is recommended to use a controller designed for this purpose, for example Flexit article number 09257.
