"A" energy class, single-room (decentralized) heat recovery ventilation with enthalpy heat exchanger, air cleaning function. Due to its wall-mountable, ductless design, it is also ideal for retrofitting. Due to two installation methods (side or rear exhaust), it can be flexibly adapted to the conditions of the room.

Clean air every moment
The ventilator ensures the cleanliness of the air with a multi-stage filter system: The combination of the pre- and middle filter, the HEPA H10 filter and the activated carbon filter achieves a PM2.5 particle filtration efficiency of up to 99%, thus cleaning the inhaled air from dust, pollen, bacteria and unpleasant odors, while the washable pre-filter on the exhaust air side contributes to long life and low maintenance. demand.

Efficient heat and moisture recovery
The device uses a cross-flow enthalpy heat exchanger, the efficiency of which reaches 82%. In winter, the warm air leaving outside warms up the incoming cold air through the heat exchanger, and in summer, the cooler indoor air pre-cools the fresh air introduced from outside, thereby providing up to 30% energy savings compared to traditional ventilation. The enthalpy heat exchanger is able to recover part of the air's humidity, so in case of high humidity it reduces the moisture content of the indoor air, but it cannot overdry it. As a result, the indoor climate remains more even and more pleasant for the user.

Intelligent air quality monitoring and automatic operation
With the built-in sensors, it monitors indoor air quality, temperature, CO2 level and humidity, and then automatically adjusts the speed of the fans installed in the device to the level of pollution. The fans equipped with an eight-speed DC motor ensure precise air exchange and quiet operation (only 23-36 dB(A)) with low energy consumption. The device maintains a slight positive pressure in the room, so fresh air always flows in through the filters, and polluted air does not enter through door or window gaps.

Smart control and automation
Thanks to the built-in WiFi connection, the device can also be controlled from a smartphone or tablet, so the settings can be conveniently accessed from anywhere. In addition, a remote control is included, so control is easy even if the phone is not at hand. The intelligent control automatically adjusts the operation to the local weather conditions, so the device always optimizes the air exchange for the current temperature and humidity. In addition, the system can be integrated into the Tuya IoT smart home ecosystem, so it works automatically in coordination with other smart devices (such as heating, cooling or dehumidifiers).
