G.A.S EC Speed Controller

Control and adjust your maximum and minimum EC fan settings using two simple knobs. By balancing the fans, you will achieve the required negative pressure. Must be connected using active cables. These cables power the device, so no separate power supply is required. 

How the controller works:

Controlling your fan speed is vital when growing indoors. As winter hits, you can reduce the intake airflow, allowing your grow room background heating (grow lights, heaters) to compensate. In summer,  turning the fans to maximum can keep air temperatures at appropriate levels. 

Comes with an active 5m male-to-male cable which allows you to connect a Vector EC fan. It has two connectors: one for your intake fan and one for your extraction fan, so if you wish to run two fans, you’ll need another active 5m male-to-male cable.

​Plugs directly into all Systemair’s AC and EC fans.
