For those who do not (yet) want to move to EC fans, we have an intelligent AC fan control module for the ELF controllers, that will control your current AC fans as efficient and quiet as possible. Gavita fan controller best speed for grow room and hydroponic system. On low speed we use burst modulated AC control to reduce losses and reduce hum in the fan motor, on higher speed settings the controller switches to phase cut control, which is more efficient in those stages. The EFM can be plugged in between your power outlet and fan, and a simple signal wire is all that is needed to control it from the ELF.
