AEROMAT Midi HY Humidity-Controlled Window Ventilator

Humidity-Controlled Window Ventilator

The AEROMAT Midi HY is a humidity-sensitive passive window ventilator designed to automatically regulate airflow based on indoor moisture levels. By responding to changes in humidity, the system helps reduce condensation and mould risk while maintaining balanced indoor air quality.

Operating on the pressure differential principle, fresh air is supplied naturally by equalising indoor and outdoor air pressure — delivering energy-efficient ventilation without electrical power. Selected 42dB acoustic models offer enhanced sound absorption, making the system suitable for urban environments and noise-sensitive developments.
