The decentralized ventilation unit with a heat and humidity recuperator, Zehnder ComfoAir 70, is perfect for installation in renovated and new buildings, apartments, student dormitories, or other premises. This device combines the highest comfort, simple operation, and a high degree of efficiency.

The main part of the device is a highly efficient enthalpy cross-counterflow heat exchanger with a heat recovery efficiency of up to 89%. This means that the unit is very efficient in the heat recovery process, helping to ensure optimal energy use.

The Zehnder ComfoAir 70 ventilation unit can also serve two rooms close to each other, providing additional flexibility and the ability to optimally adapt the ventilation system to the needs of a specific building or room. In addition, an additional supply or exhaust duct can be connected at the end of the unit, increasing its functionality and adaptability to specific ventilation needs.

The Zehnder ComfoAir 70 mini-recuperator is designed for the ventilation of smaller apartments or separate rooms without piping. Due to the unique design of the equipment, all noise-producing components are hidden in the outer walls. The entire body of the device is in a polypropylene mold, which guarantees an extremely good noise barrier and sealing performance.

The Zehnder ComfoAir 70 has a Passive House certificate.
