G.A.S EC5 Fan Controller – Thermostatic EC Fan Speed Controller with Reactive Temperature Technology

The G.A.S EC5 Fan Controller gives you complete control over your intake and extraction system, allowing you to fine-tune your grow room environment with precision. Control your EC fans thermostatically, balance intake and extraction to achieve perfect negative pressure, and prevent unwanted odours from escaping — all without a separate balancer.

The EC5 features Reactive Temperature Technology (RTT), a built-in microchip developed specifically for indoor climate rooms. RTT monitors temperature continuously: if there’s a sudden spike, the controller reacts quickly to stabilise conditions; if there’s a gradual rise, fan speed increases proportionally. The result is a stable, efficient environment with minimal manual intervention.
