The Quick and Easy Way to Control Two EC Fans Controlling your intake and outtake EC fans has never been easier with the EC Speed Controller from Global Air Supplies. The EC Speed Controller sets your intake and outtake fan speeds, allowing you to balance both fans to create the required level of negative air pressure. How the GAS EC Speed Controller Works Controlling your fan speed is critical when growing indoors throughout the year. As cold temperatures hit, it's handy to be able to reduce intake airflow a little, allowing your grow room background heating (from grow lights and heaters) to compensate. The same can be said for hot summer months, where outside temperatures can play havoc with your indoor environment. In this case, turning up the fans to maximum can help to keep air temperatures at appropriate levels. The GAS EC Fan Speed Controller from Global Air Supplies regulates two EC fans from one device by using the variable control knobs. The EC Speed Controller plugs directly into any fans in the Systemair range that feature active cables (Systemair EC cables using white connectors). These active cables power the device, so there's no need for a separate power supply. This small but perfectly formed controller represents great value for money!
