Fan Speed Controller Rig
Starting at: £11.95
A useful bit of kit. Often growers buy a large fan to cope with the summer heat and then come winter it proves too powerful, bringing in too much cold air. The clever Fan Speed Controller Rig allows you to adjust the speed of your fan, so your plants don't get icy blasts! It will comfortably control all our RVK Fans except the RVK315 L1. Not suitable for use with 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.
