"A" energy class, single-room (decentralized) heat recovery ventilation, it is characterized by simple installation similar to standard wall fans, in the case of new and traditional buildings, it can even be installed afterwards.

Energy efficient air exchange with heat recovery
The heart of the device is a highly efficient ceramic heat exchanger, which can achieve a heat recovery efficiency of up to 97%.

Smart, wireless control
Holtop's ventilator stands out in its category with the fact that the control is completely wireless, the devices can be synchronized without cabling, automatically switching between supply and extraction modes, thus ensuring balanced air exchange throughout the room.

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 also be integrated into the Tuya IoT smart home ecosystem, so it works automatically in coordination with other smart devices (for example, heating, cooling or dehumidifiers).

Automatic shutter for perfect comfort
A practical solution is the motorized, automatic shutter, which closes when the device is turned off, this prevents cold air, dust, insects or noise from entering the living space, while the operation takes place automatically, without user intervention. When the fan starts, the louver opens automatically, so the air exchange continues smoothly.

Quiet operation and low consumption
The fan works with a low-noise EC motor, which ensures low energy consumption and a long service life.

Healthy and clean air
The device has an antibacterial coated ceramic heat exchanger and easily replaceable filters that capture dust and pollens, improving indoor air quality. With the built-in humidity sensor, the ventilation automatically adjusts to the air quality.
