Many units can be connected to one control network. High heat recovery efficiency of up to 90 % is achieved due to the use of a cellular regenerator. The design of the unit provides easy maintenance and installation.
Noise-insulating material provides noise absorption during the operation of the ventilator. It is enough to have only one ventilator operating in regeneration or ventilation mode to provide ventilation in the room. The unit can be controlled via remote control and buttons on the control panel. Flexible customisation for each user via an app on the smartphone.
  • The unit modes are controlled via the sensor control panel located on the casing of the unit, via the remote control or the smartphone.

Operation modes:

• Speed setup   

• Operation mode setup

   - Ventilation 

   - Regeneration 

• Timer setup

   - 4 hours at speed III 

   - 8 hours at speed I 

The control buttons are also duplicated on the ventilator casing:

• ventilation with energy recovery 

• ventilation 

• speed switching and ventilator turning off 

It is possible to control all the ventilators simultaneously by connecting them to a single Wi-Fi network.
In this case, all ventilators (Slaves) will respond to a signal from the Master ventilator only.
TwinFresh Style WiFi units can be combined into one control circuit.


Trendy ventilator design. High efficiency – 90%.
Can be mounted inside a prepared hole (from ∅170 mm) in a wall. A humidity sensor.
Connection of the units into one control network via WiFi. Connection of an external CO2 sensor or other external relay sensors.
Automatic drafts shutoff when the ventilator is off due to the air damper. Sound pressure level from 1 to 26 dBA at a distance of 3 m.
Ventilation of premises with the area of about 25 m2 (the area is approximate and depends on the ventilation standards in your country). Simple mounting and maintenance.
  • To preserve indoor heat, the ventilator operates in regeneration mode with two cycles, so that heat is returned to the room, the humidity balance is maintained, and the load on the heating system in winter is reduced.
  • To ensure energy efficiency, the ventilator operates in energy recovery mode with two cycles, thereby reducing the load on the air conditioning system in summer.
