Northvent Expert DUO A30-1 Pro


Heat recovery single-room units. Maximum air capacity up to 30 m³/h.


Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises.Reducing heat losses caused by ventilation due to heat recovery. Humidity balance and regulated air exchange create individually controlled microclimate.Coordinated network based on several integrated single-room ventilation units with central control.
Easy maintenance.
Indoor unit is opened by pressing the latches on both sides.
One of the best regeneration efficiency on the market due to innovative hexagonal structure of the heat exchanger cells.
One fan supplies fresh and cold air from outdoor, which flows through thecorrespondent part of the ceramic regenerator and absorbs accumulatedheat and humidity.At the same time, another fan extracts slate and warm air from indoor, that flows through the other part of the ceramic regenerator and transfers heat energy and moisture to it. After 70 seconds operation the fans change the rotation direction and opposite processes start.
Control of the unit operation mode is performed by means of the sensor control panel located on the unit casing or the remote controller.  
Expert DUO either can operate as independent unit or can be wired with other units in a house and controlled with a master unit. In this case, only the master unit receives a signal from the remote control. Expert DUO is equipped with a humidity sensor for indoor humidity control. If humidity increases above a set point, the unit boosts to the high speed independent of other units in the system.
The unit is designed for through-the-wall installation inside a prepared core hole in an outer wall of the building. Expert DUO must be installed in each room with high humidity like kitchen, bathroom to be ventilated while Expert must be installed in each living room to be ventilated.
