Swap stale air for fresh air

The ComfoAir 70 is the decentralized, compact comfort ventilation unit with heat recovery from indoor climate specialist Zehnder.

It has been specially designed for the ventilation of one or two-room apartments. It is also ideal for installation situations in which larger living areas are to be ventilated with several devices distributed throughout the rooms. Thanks to its simple installation, the ventilation unit is ideally suited for renovation projects, but is of course also an option for new builds.

The inner contours of the ComfoAir 70 are formed by a 10-part set of molded parts made of expanded polypropylene. The individual components fit together exactly and are permanently bonded to each other, in some cases using a thermal joining process. This is done without any additional material. In this way, even thin walls can be joined airtightly.

The EPP chassis provides good leakage values and ensures optimum heat and sound insulation.
