13 Amp Control Freak Dynamic Frequency Fan Controller
£395.00 incl. Vat
Cut energy costs & prolong the life of fans without any buzzing! Get your hands on a Control Freak! It’s a real smooth operator!
It won't clip or distort your wave form like other AC fan controllers – it changes your frequency.
This means fans last longer, you save energy and there’s no noise – not even buzzing - it’s freaky!
It’s easy to reach and stay within your target temperature - there are 90 fan speedssettings (from 10 – 100%)! Your fan will move through speeds smoothly.
For complete control, you can change your bandwidth (hysteresis). Set a tight bandwidth for precise temperature control. Or set a loose bandwidth for a smoother speed.
Save Energy
You use far less power at a slower speed - your power use drops by as much as your fan speed. So when running fans 50% slower, you use 50% less power. Most fan controllers use way more power than this!
- 2 x sockets (for intake & extraction fan)
- Silent – no buzzing!
- Low power – especially at slower speeds - mega savings ahead!
- 90 fan speeds (from 10-100%) for super smooth speed control

90 Speed Settings
You get 90 speeds from 10% - 100%! It’s easier to reach your target temperature and fans run smoothly!
Connect Multiple Fans
Your controller has two sockets. Use it to run an extractor fan and intake fan from one controller. You can even use an extension lead for multiple intake fans. Just make sure you stay within the amp rating!
Bandwidth Control
Your bandwidth is how much your temperature can rise above your minimum.
Use a tight bandwidth to keep your temperature closer to your target. Or set a wider bandwidth to keep your fans moving smoothly.
Easy To Use & Set Up
Everything’s plug and play, and you have a large LCD display!
