The decentralised ventilation unit Zehnder ComfoAir 70 provides fresh air and produces a pleasant indoor climate and feeling of well-being. Thanks to its intelligent technology, fresh air is supplied to the room permanently and stale, moist air exhausted to the outside – so you never have the feeling that you have to open the window. This reduces the energy consumption because no valuable heating energy is lost through window ventilation. This saves energy and real money.
