The XFLAT 350-450 is a central ventilation unit for houses or flats with a nominal airflow in the range of 300-450 m³/h. It offers a high efficiency heat exchanger for heat recovery (optional heat and humidity), a very low construction height and a lightweight EPP design. Thanks to the "MultiPlacing" mounting, it can be installed in multiple positions (wall, ceiling) even in smaller technical spaces.
High energy efficiency, the possibility of connecting a CO₂ or humidity sensor, integrated preheating and easy filter change (M5 or F7) make it a modern solution for ventilation with heat recovery.
