The 12 V double ventilator is waterproof to IP55. It is equipped with a functional rack mounting set and an intelligent external aluminium control unit, which can be used to adjust the speed in two ways: Via a manual 6-stage setting and via a temperature-dependent, sensor-controlled automatic system that switches off downwards at 20 °C and operates at maximum speed at 45 °C. The integrated timer allows 6 different start-up times. Despite the strong cooling effect, the ventilator works very quietly. The ventilator has overvoltage protection integrated in the control unit and can be easily operated in the 12 V on-board power supply.
