Rhino Fan Speed Controller

The Rhino Fan Controller is a convenient and simple way to quietly control fan speeds in your grow room in order to manage temperature and maintain negative pressure.

The RC-1 controller isn’t silent, but it can still reliably control both intake and extraction fan speeds to maintain temperature and negative pressure.



Growers can set their desired room temperature and be confident that if the temperature in their grow room becomes too high both fans will speed up to maintain negative pressure. When this clever bit of kit recognises that the desired temp has been met it will allow fans to slow down to the minimum set speed.
