I control a Ruck 125mm ISO Acoustic fan (from JF's) with this controller - no harmonic hum detectable at low speeds, at all! Great. High quality product - good service from JF's, Thanks
Use this to control my Mini box fans, works perfectly and is silent.
Unbelievable! With TDmixvent500: noise reduction minimum 50% !!! In position 1 we wonder is on or off the fan? Money well spent !!! Thank you!
Incredible, Perfect, Silent and Fast delivery ! Thanks "Just Fans" and Thanks "SystemAir"
