The G.A.S EC5 Fan Speed Controller from Global Air Supplies allows you to control every aspect of your intake and extraction system, enabling you to fine tune your setup for the perfect environment.
 
Not only will you be able to control your fans thermostatically, you also have the ability to balance your fans to achieve the perfect negative pressure, preventing any unwanted odours from escaping your grow space without having to use a separate balancer.
 
The EC5 Fan Controller features Reactive Temperature Technology (RTT). Developed specially for indoor climate rooms, the controller features a built-in microchip that stands guards over your climate room. If there is a sudden spike in temperature the controller will react quickly, stabilising the temperature. If there is a small rise in temperature, the controller will increase the fan speed gradually.
 
Easy to set up and use, just plug straight into your EC fan with no power packs required. The EC5 Fan Controller plugs directly into any of the systemair EC fan range.
