The Global Air EC Digital Fan Controller is designed to give growers precise control over ventilation in indoor growing environments. Built specifically for Systemair EC fans, this intelligent controller automatically adjusts fan speeds based on temperature changes, helping maintain a stable climate inside your grow tent or grow room. Stable airflow is essential for healthy plant development, efficient nutrient uptake, and strong yields in hydroponics, coco, or soil systems.
Using reactive temperature technology, the controller continuously monitors the grow environment and automatically increases or reduces fan speed when temperatures change. This ensures hot air is removed quickly while preventing unnecessary fan operation, improving energy efficiency and reducing wear on your ventilation equipment.
Key Benefits
• Intelligent thermostatic control of EC extractor and intake fans
• Reactive temperature technology automatically adjusts fan speed
• Helps maintain stable climate conditions in grow tents and grow rooms
• Reduces energy consumption and equipment wear
• Compatible with Systemair EC fan ranges
• Can be paired with a fan balancer for precise intake and extraction control
• Simple digital interface for accurate environmental adjustments
How It Solves Grow Problems
Temperature fluctuations are one of the most common challenges in indoor growing. Excess heat from grow lights can quickly build up, especially during vegetative growth and the flowering stage, leading to plant stress, poor nutrient uptake, and reduced yields.
The EC Digital Fan Controller automatically adjusts ventilation to stabilise the environment before conditions become harmful. By increasing airflow when temperatures rise and slowing fans when conditions stabilise, it helps maintain consistent climate control inside the grow space. This balanced airflow supports healthy transpiration, improves plant health, and helps growers achieve stronger vegetative growth and denser flowers during the bloom stage.
How to Use
-
Connect the EC Digital Fan Controller to your compatible Systemair EC fan.
-
Install the temperature probe inside your grow tent or grow room at canopy level.
-
Set your desired temperature target using the controller interface.
-
The controller will automatically adjust fan speeds as temperatures change.
-
For enhanced airflow balance, connect the controller to a compatible fan balancer to coordinate intake and extraction fans.
