This range of transformer controllers for single phase AC fans and motors provide energy saving speed control without the creation of additional motor noise which you get with most electronic controllers.
Vacuum impregnation further reduces electrical noise from the transformers.

The R.E range of controllers are available for total load currents of up to 7.0 amps,
A rotary switch selects one of five different voltages.

The silent R-E Transformer controller produce no buzz on the fans, unlike electronic speed controllers, due to providing a smooth sine wave to the motor. Also lengthens fan life. Used for a truly silent fan setup.

For 2 speed trickle and boost version see the REU.
For fans with inbuilt TK connections or for use with thermostats see the RTRE.

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

Unbelievable! With TDmixvent500: noise reduction minimum 50% !!! In position 1 we wonder is on or off the fan? Money well spent !!! Thank you!
