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.
One of the best
regeneration efficiency
on the market due to
innovative hexagonal
structure of the heat
exchanger cells.
Integrated automatic airshutters prevent air backdrafting. Built-in Wi-Fi for wireless communication between units
and Android or iOS device control. 
Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers its heat energy and moisture to it.As the ceramic regenerator gets warmed up, the unit switches to the supply mode. Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity.When the ceramic regenerator is cooled down, the unit switches to the extract air mode.
The units can be connected by Wi-Fi for synchronized operation.

The units can be connected by Wi-Fi. Northvent PRO app for Android or iOSdevices is available at Google Play and AppStore.

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 connected 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 regenerator, the fan and the filters.
