Fan Speed Voltage Controllers
Starting at: £109.95
Our endless endeavours to bring you the best new products around have once again yielded exciting returns in this fantastic range of Fan Speed Voltage Controllers! While resistor-based controllers can cause fans to produce additional noise as they change speeds, these models use a variac to regulate voltage and subsequent airflow without generating noticeable side effects. Both Voltage Controllers are flexible featuring a five-speed setting that alters output by 20% intervals and come in cheaper than the Airforce models that they replace! Impressively, the 6 amp controller is also the only one we could find that even works with the largest acoustic fans!

Fan Speed Controllers
Seasonal temperature fluctuations mean that you won't always need your extractor fans to run at full speed. This is where a fan speed controller comes into its own allowing you to precisely adjust your fan speeds (and therefore extraction rates) to perfectly balance intake and extraction rates to maintain the perfect temperature. There are a number of ways of adjusting the speed of a fan, and the cheapest and most prevalent method is with a resistive type controller. these controllers in crease resistance and slow the fans that way. This can cause additional noise to be created by some fan models. The other way is a voltage controller which uses a variac to alter the actual power supplied to the fan. These controllers are much more heavy duty and do not create any additional fan noise, but they are significantly more expensive.
