The intelligent, stylish, multi-purpose O2 and O2 Supreme residential fans by Blauberg Ventilatoren offer an optimal set of features that make them the best solution for creating a comfortable indoor climate in bathrooms, toilets and other living spaces with minimum noise and power consumption.


The O2 and O2 Supreme fans feature high air flow rates (up to 140 m3/h) and very low noise levels (from 9 dBA). This performance is achieved by using a modern DC motor and an aerodynamically optimized impeller shape. The fans have a neat design and are available in white and black colors, which allows them to fit harmoniously into any interior.

The fans are equipped with humidity, light, temperature, and motion sensors, which make it possible to select and change operating modes depending on air quality, light levels, and the presence of people, thus maintaining a comfortable indoor climate at all times. For example, the fans automatically determine the trigger threshold for the humidity sensor and respond only to sudden changes in the indoor humidity level, ignoring seasonal fluctuations. Operation modes of the device also change with a sharp change in the indoor light level, while smooth changes in light level during the day are ignored. The temperature sensor responds accordingly to changes in the indoor air temperature: it turns on when the temperature reaches 28 °C and turns off when the temperature drops to 24 °C. All sensors work together to create the most balanced and comfortable indoor climate.

Both fan models provide the user with extensive control options. The operation of the O2 fan is controlled via the built-in control panel. The O2 Supreme model has a built-in Wi-Fi module that makes it possible to control the device using a smartphone and the Blauberg Home mobile app, as well as via the cloud service. Thanks to the Google Home and Alexa voice assistants, the O2 Supreme can be controlled using voice commands.

The fans have eight operating modes, which can be selected using a multi-position switch on the motor and impeller unit. For example, the fan can be constantly in standby mode or operate in ventilation mode at a minimum speed, but when a motion sensor or humidity sensor is triggered, it can autonomously switch to a higher speed and higher air flow.

The O2 and O2 Supreme fans have minimal power consumption (only 2.7 W at maximum speed) and a high degree of protection against moisture, which allows them to be installed directly above the showers. Another advantage of the ventilation device is its ease of maintenance: the motor and impeller unit can be easily removed with no special tools needed.
