Fresh-r 55-D Forward is a silent room-to-room fan that, on demand, blows stale or polluted air towards the Fresh-r, the decentralized heat exchanger. It continuously measures whether humidity in the air increases or oxygen decreases. Only when this happens the Fresh-r Forward starts (or increases) ventilation.
The Fresh-r Forward is a whisper-quiet fan that moves air from one room to another, towards the Fresh-r heat exchanger.
