The AIRUNIT GEMINI is a residential ventilation unit with heat recovery and an additional exhaust air function. In heat recovery mode, the room is ventilated in a balanced way, ensuring a pleasant indoor climate and consistently high air quality.

In this fully automatic and sensor-controlled operation, the AIRUNIT GEMINI continuously monitors the humidity of the exhaust air and, if necessary, independently increases or decreases the power level in heat recovery mode from 5 to 30 m³/h. Should the increased airflow in heat recovery mode be insufficient to remove the accumulated moisture, the unit switches to pure exhaust air mode at 40 m³/h until the normal level is reached again.

The AIRUNIT GEMINIis equipped with two fans, two heat exchangers, and two ISO Coarse 50% (G3) filters. This paired fan configuration means the AIRUNIT GEMINI not only meets the requirements for use in exhaust air rooms, but is also the perfect single-room solution for larger rooms of 20 m² - 25 m².
