Our standard range of AC axial fans work best when not speed controlled, if however you wish to reduce the speed we advise not reducing the voltage below 180V, below this voltage the life span of the fan will be seriously reduced and warranty will be voided. If your application requires further speed restriction we suggest one of our EC axial fans.
