Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises.Heat recovery minimises ventilation heat losses.Humidity balance and controllable air exchange create individually set microclimate.Coordinated network based on several integrated single-room ventilation units with central control.



High-tech ceramic energy accumulator with heat recovery up to 90 %.

Due to its cellular structure it has a larger heat transfer area surface and high efficiency.


Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers a part of the accumulated heat and moisture to it.In 70 seconds, after heating of the ceramic regenerator, the unit switches to the supply mode.

Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity.In 70 seconds, after cooling of the ceramic regenerator, the unit is switched to the extract air mode.


The unit operation mode control is performed by means of manual three-position switches located on the unit casing or using the remote controller.The unit is equipped with a humidity sensor for indoor humidity control and regulation.Connection of the units into one ventilation system provide balanced ventilation and central control.Remote control and operation mode selection:

Connection of several units in series enables their synchronous control by the first unit. The signal from the remote control is received by the first unit only.


The unit is designed for external through-the-wall installation inside a prepared round hole in the outer wall of the building.The best ventilation solution is pairwise installation of reverse phase connected units. Some units supply fresh air to the room and the other units extract stale air from the room. This allows to arrange the most efficient balanced ventilation.

In case of brand new construction the units are mounted in two stages:

  • pre-installation at the stage of the indoor finishing and outer decorative wall finishing. It includes installation of the telescopic air ducts, outer ventilation hood and laying out of electric cables.
  • final mounting before commissioning of a house. It includes installation of the regenerator, the filters, connection of the ventilation unit.

If mounting of the ventilation hood on the outer wall is undesirable it may be flush mounted and the external grille may be inserted into the outer window jamb using the KIT BlauPlast 204x60-1 pre-installation kit. Available upon separate order.
