Global Air - EC Dimmer (Cable Pack 32) – Manual Fan Speed Controller

Simple, direct speed control for a single EC fan

The Global Air EC Dimmer (Cable Pack 32) is a manual controller for adjusting the speed of a single EC inline fan, giving growers hands-on control of ventilation without sensors or programming. It suits anyone who wants quick, reliable extraction control in a grow tent or grow room, and is compatible with the Systemair EC fan range.

Key Benefits

• Manual speed control for a single EC inline fan via a simple dial.
• Plug-and-play design for quick installation, no configuration needed.
• Compact and durable controller with a small footprint.
• Compatible with the Systemair EC fan range.
• Suitable for hydroponics, coco and soil indoor growing setups.

Fixing fans that run too fast or too slow for the room

With no way to adjust airflow, a fixed-speed fan can leave a grow room too hot, too humid or unnecessarily noisy. The EC Dimmer lets you dial speed up or down to match conditions: lower for quieter running and steadier humidity, higher to clear excess heat quickly, holding temperature and humidity consistent for healthy nutrient uptake and strong yields.

How to Use

• Connect the EC Dimmer to your EC fan using the supplied cable pack.
• Confirm the fan is compatible with Systemair EC fan systems.
• Place the controller in an accessible spot near your ventilation setup.
• Turn the adjustment dial to set the desired fan speed.
• Monitor grow room conditions and adjust airflow as needed to keep temperature and humidity stable.
