Decentralized wall-mounted heat recovery unit ComfoAir 70 wall cover in white plastic 527007240

Wall-mounted heat recovery unit providing comfort and energy savings

The Zehnder ComfoAir 70 is a decentralized ventilation unit with heat and moisture recovery, ideal for both the modernization of existing buildings and new investments. The unit provides a performance of 15 to 65 m³/h, and its compact dimensions allow for easy installation in various rooms – apartments, student dormitories or offices. Thanks to the use of a cross-current enthalpy exchanger, the heat recovery unit achieves high heat recovery efficiency – up to 89%, which translates into real energy savings. Importantly, the device does not require condensate drainage, which simplifies installation and reduces costs.

Why choose Zehnder ComfoAir 70?

• High efficiency: Heat recovery up to 89% and moisture recovery up to 79% minimizes energy losses and ensures a comfortable indoor climate.
• Simple installation: The compact design and no need to connect to a condensate drain facilitate installation, especially in difficult renovation conditions. Requires a 250 mm diameter wall penetration.
• Quiet operation: The use of high-quality fans ensures almost silent operation of the device.
• Versatility: Possibility of serving two adjacent rooms by connecting an additional supply or exhaust air duct to the rear of the housing.
• Easy maintenance: The heat exchanger can be easily cleaned with warm water, and the filters are easily accessible from the front of the device.
• Control: The control panel on the housing allows you to adjust the operation of the device. Possibility of expanding control by installing additional humidity sensors, VOC (volatile organic compound) sensors or CO2 sensors.

Construction and application

The unit is equipped with a cross-current enthalpy exchanger, which recovers not only heat but also moisture, preventing the air from drying out during the heating season. The housing is made of powder-coated aluminum and expanded polypropylene (EPP), which ensures durability and good insulation properties. EC (electronically commutated) fans are characterized by high efficiency and low energy consumption. The integrated air inlet and outlet are in one element, which simplifies installation and minimizes heat loss.

The device is designed for wall mounting and requires a 250 mm diameter hole. An external wall cover made of plastic (white color) is available, which protects the device from the weather and gives it an aesthetic appearance.

Zehnder ComfoAir 70 is an investment in a healthy climate in your home and real energy savings. The device meets safety standards and is covered by the manufacturer's warranty.
