ComfoAir Flex 350 Heat recovery ventilation unit 250 471234270

Compact heat recovery ventilation for home and apartment

The ComfoAir Flex 350 is a central heat recovery ventilation unit designed for efficiency and space saving. The device is ideal for both new and modernized residential buildings, providing a constant supply of fresh air and reducing heat loss.

Thanks to its compact dimensions (1068 x 868 x 327 mm) and the possibility of suspended mounting, the recuperator will discreetly blend into the interior architecture.

Technology for comfort and savings

At the heart of the device is a high-efficiency cross-countercurrent heat exchanger, which allows for the recovery of up to 95% of the heat from the exhaust air. This translates into significant reductions in heating and air conditioning costs. Additionally, the recuperator is equipped with a 2 kW modulated pre-heater and a bypass, which allow you to adjust the device's operation to current weather conditions and user needs. Flow Control technology ensures optimal airflow, and the Climate Switch function automatically adjusts the recuperator's operation to the season – preventing overheating in summer and maximizing heat recovery in winter.

Intelligent control and easy installation

ComfoAir Flex 350 offers full control over the ventilation system thanks to the built-in Wi-Fi module. The ability to control via the Zehnder ComfoControl smartphone app allows you to remotely monitor the device's operating parameters and adjust settings to individual preferences. The installation of the recuperator is simple and flexible – four rotating spigots allow connection of ventilation ducts from different sides, and adjustable mounting sets facilitate installation in various configurations. The maximum air volume at 100 Pa is 281 m³/h, which ensures effective air exchange in the rooms. The device is characterized by a minimal noise level, which guarantees comfortable use.
