Fresh Air
We can meet all your residential ventilation needs: Perfectly planned, perfectly installed – for your maximum satisfaction. Anyone purchasing a comfort ventilation system wants one thing above all else: fresh air at all times, without having to worry about the details. This requires a system that works. We can meet this need with expert planning and installation and a complete modular system consisting of a ventilation unit and air distribution. With our products, you benefit from our experience and a uniquely comprehensive product portfolio. You can be assured of best possible planning, fastest possible installation and maximum functionality. This will make your work significantly easier and your customers can be assured of a reliable system with a long service life.
Comfortable indoor ventilation systems ensure sufficient and healthy air exchange independently and around the clock. Far too often, however, newly built or modernized building envelopes no longer allow natural air exchange through cracks and joints. Sufficient, repeated purge ventilation in all rooms is not feasible for most people in everyday life. Particularly in large cities, opening windows also means fine dust, pollution or exhaust fumes.
This is where ventilation systems come into play. They transport clean, fresh air indoors – without any annoying pollen or impurities. In addition, excess humidity in the rooms, and thus the formation of mold, is prevented, which protects not only the health of the occupants but also the value of the property.

Our ventilation technology automatically ensures that only fresh, clean air enters your home. Disturbances caused by open windows, such as street noise or annoying flies and other insects, are eliminated.
Ventilation technology removes not only stale air, but also pollutants emitted from furnishings. The decrease of excess humidity reduces the risk of mold on walls and furniture.
The heat exchanger in our ventilation unit extracts the residual heat from the stale air and uses it to heat the fresh air from outside, which saves a lot of energy and money during the heating season.
Individual ventilation units provide a pleasant, feel-good climate in the rooms of the residential unit – without an air distribution system. Ideal for renovating individual rooms and apartments. The installation is quick, uncomplicated, and cost-effective.
The decentralized 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.
Energy-efficient: The large dimensions of the enthalpy exchanger ensure optimal heat recovery and humidity recovery.
Flexible: Neighboring rooms can also be integrated into the ventilation system.
Expandable: Large apartments can use several units to supply and extract air.
Intuitive: Capacitive button for easy touch operation.
Demand-oriented: Four programmable fan levels and switch-off function to ensure the ideal air flows.
Safe: Display shows filter replacement and any service requirements.

Of course – we all know the pleasure of flinging open the windows on a lovely day! This aside however, the system is designed to optimize indoor air quality at any time of the day or night in all weathers without having to worry about external noise ingress or security considerations.
A ventilation system with heat recovery decreases your energy consumption when compared to standard alternatives. As well as recovering heat which would otherwise have been exhausted to atmosphere, our systems use energy efficient DC motors to limit energy consumption in every way.
On the contrary: compared to window ventilation, with Zehnder comfortable indoor ventilation, the energy effect of the airtight building envelope is fully utilized. With up to 96% heat recovery, up to 50% heating energy can be saved.
