G.A.S AC-EC Digital Fan Controller – Combined AC & EC Fan Control with Day/Night Settings

The G.A.S AC-EC Digital Controller is the ultimate fan controller for grow rooms running a mix of AC and EC fans. It regulates airflow based on temperature and humidity, with separate day and night settings — so your environment stays perfectly dialled in around the clock.

With two 5-amp sockets (one for intake, one for extraction), a built-in fan balancer for accurate negative pressure, and a light sensor that automatically detects your lighting period, the AC-EC removes the need for manual adjustments and keeps your grow room running efficiently.
