Northvent Expert A50-1 W V.2


Single-room heat recovery units with Wi-Fi control. Maximum air capacity up to 50 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 controllable air exchange create individually controlled microclimate.Wi-F i data exchange between several single-room ventilation units for coordinated operation.Controlled by Android or iOS smartphone or tablet.
One of the best heat recovery efficiency on the market due to innovative hexagonal structure of the heat exchanger cells. Built-in Wi-Fi for wireless communication between units and Android or iOS device control. Integrated automatic air shutters prevent air back drafting. Easy maintenance. Indoor unit is opened by pressing the latches on both sides. The specially designed front panel can be closed manually to ensure 100 % air tightness and protect against wind impact.
Warm stale air is extracted from the premise, flows through the ceramic heat exchanger and transfers its heat and moisture to it. As the ceramic heat exchanger gets warmed up, the unit switches to the supply mode.Clean cold intake air flows through the heat exchanger and absorbs accumulated heat and humidity.When the heat exchanger is cooled down, the unit switches to the extract air mode.
Unit control via smartphone or tablet application. The units can be connected by Wi-Fi for synchronized operation. House ventilation control via cloud service from anywhere in the world.
Expert A50-1 W V.2 either can operate as independent unit or can be connected 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.

Northhvent V.2 app for Android or iOS devices is available at Google Play and App Store.

Connection to smart house or Building Management System (BMS) via Wi-Fi. Control of the unit operation mode is also performed by means of the  sensor control panel located on the unit casing or the remote control.
Expert A50-1 W V.2 is equipped with a humidity sensor for indoor humidity control. If humidity increases above a set point, the unit boosts to the high speed independently on other units in the system.
The unit is designed for through-the-wall installation inside a prepared hole in an outer wall of the building. The best ventilation solution is pairwise installation of reverse phase synchronized units. Some units ensure supply of fresh air to the room and the other units extract air from the premise. This way the most efficient balanced ventilation is arranged. In case of brand new construction, units are mounted in two stages:

  • Pre-installation of an air duct and an outer ventilation hood at the stage of indoor finishing and outer decorative wall finishing.
  • Completion of the installation before commissioning of a house. It includes installation of the indoor unit with controller and shutters, the cartridge, the heat exchanger, the fan and the filters.
