Variispeed Fan Controllers are easy to use, high quality fan controllers for controlling single fans with AC motors (you will know if you have an EC fan by the hole in your pocket!).
They can control the fan from 0-100% (though most fans should be run at 35% plus when using this technology) and can take up to 300W, which covers all of the RUCK fans that we sell – for other fans please check the specifications to see how much power they draw. Depending on the fan you use there may be some humming, but at this price point most people tend put up with it…
The Variispeed is well built, simple to use and very cheap – they are a great way of taking the edge off slightly too powerful fans without need to replace the whole unit.
