Rhino Silent Fan Speed Controllers are developed and manufactured in the UK to the highest standards these controllers will eliminate buzzing and humming to ensure silent climate control.
Silently controls both intake and exhaust fans, allowing negative pressure to be maintained.
Housed in durable steel casing with a galvanised back panel ready to hang either inside or outside of the grow room.
Manually adjustable through five different voltage levels corresponding to fan speeds, the advantage of the voltage stepper over variable resistors is the lack of hum created by the resistance.
As well as being unwanted noise, this hum is also a sign that the capacitors in the fan are being put under strain and their lifespan is being reduced. This is especially true when a variable resistor is used with the larger inline fans.
