EC Speed Controller

If you have been looking for the ideal and convenient way of controlling the speed of two separate EC fans, the GAS EC speed controller is the solution that you’ve been looking for. Since it is powered directly from your fan itself, you won’t need to provide an additional power supply for ease of setup, and since it directly plugs onto any fan from within Systemair’s EC range and is connected using Active Cables, it is the perfect choice when you need to set the intake and outtake fan speeds precisely to get the right balance to achieve optimal negative pressure.
