Variac Fan Speed Controller
The Variac Fan Speed Controller is a silent, auto transformer, fan speed controller which is compatible with most speed controllable extraction fans.
The purpose of the Variac Fan Speed Controller is to help you reduce or increase the amount of air extraction that’s required, for example during lights off, you may not need the same amount of air exchange that’s required during lights on, therefore the fan speed can be reduced during this period then increased again when the lights come back on.
With 5 voltage speeds available, which are set using a robust switch on the front of the unit, the Variac Fan Speed Controller will not make your fan hum, in fact Variac says it completely eliminates harmonic fan motor hum, its also protected to IP54 standards, meaning it’s suitable for use in humid environments, such as an indoor grow room.
The Variac Fan Speed Controller is available in 1.5, 3.5, 5 & 10 amp ratings and has the following advantages:
- Silent, auto transformer fan speed controller
- Features 5 voltage speed settings
- No harmonic fan motor hum
