The Benefits of Zehnder Ventilation

Zehnder Comfosystems provide the ideal solution for air tight buildings in which the windows often remain closed due to noise or dust particles – a situation which is increasingly common in the design and location of modern buildings. Zehnder Comfosystems promote a sense of well-being among the occupants and help retain the value of the property. With heat recovery from the extract air, the system provides not only good air quality, but also pre-cooled or pre-heated air, depending on the season.

  • Continuous supply of fresh air promotes good health
  • Saves energy through heat recovery
  • Retains property value by preventing mildew
  • Protects against outside noise


Fresh air promotes well-being, healthy sleep, concentration and productivity. Draft-free air helps to prevent colds and is good for your health. Thanks to optional fine filters, which capture fine dust and pollen, even allergy sufferers can breathe easily. An enthalpy heat exchanger for moisture recovery can prevent the air from getting too dry in winter.

  • Optimum oxygen supply and draft-free air promote well-being
  • Hypoallergenic and reduces respiratory disorders. Prevents outdoor pollutants entering rooms thanks to fine filters and extraction of indoor pollutants
  • Prevents mildew formation
