Warm and stale air out, fresh and clean air in: Dometic FanTastic Vent does it in a matter of minutes. It’s pleasantly quiet and energy saving, too. The core of this truly fantastic ventilation solution is a high performance rotary fan and thermostat which are firmly integrated in the roof window and can be adjusted as required. Simply set the desired temperature on the remote control and the fan motor will start and stop automatically as the interior temperature of the vehicle exceeds or drops below the selected temperature level. FanTastic Vent works with the roof window slightly open to create a pleasant, draught-free air flow. A handy rain sensor will automatically close the dome when it starts to rain, keeping you and your vehicle interior dry with minimum fuss.
