The EC-fan (electronically commutated motors) has a diameter of 160mm, it is a very powerful fan with 1'180m³/h at 0[Pa]. The EC fan has the characteristic that he makes no hum on the low rotation and fulfills the required efficiency law by 2018. A built in LCD display with keyboard and power led allows a very easy setting and reading of all the information given by the fan such as actual set speed, temperature, humidity day/night and rounds per minute of the motor. A built in light sensor in the probe recognizes day/night modes. The Ventilator comes with 1.5m power cable and 4m sensors cable, it is ready to use.
