"A" energy efficiency class, central (centralized) heat recovery ventilator, can be placed in the attic, on the ceiling or above the false ceiling, in a horizontal design. Suitable for continuous or intermittent operation, energy-saving, dust- and other pollutant-free ventilation of some rooms of family houses, apartments, offices, max. In the case of a floor area of ​​220 square meters.

The internal structure of the device was designed with EPS insulation, the higher efficiency in order to prevent lower energy consumption and condensation.

Its energy-saving DC motor can operate with up to 70% lower power consumption compared to standard solutions, which can mean significant energy savings.

The radial fans located in the unit have direct drive and dynamic balancing for quiet and vibration-free operation.

The 3rd generation cross-flow enthalpy exchanger is made of the latest nanofiber structure to ensure greater efficiency. The material of the heat exchanger is mold resistant and fire retardant. It is easily accessible and can be easily cleaned with a vacuum cleaner.

The product has an LCD display controller and a Wifi module. It can also be controlled from a smartphone (iOS and Android) with a free downloadable Hungarian-language application.

The cleanliness of the air entering the ventilated room is made possible by the G3 and F9 filters, which are already included in the device. The F9 filter removes fine particles from the air very efficiently (especially the PM10 /dust, pollen/, PM2.5 /smog particles, combustion products/ and PM1 /very fine dust, soot, bacteria/ fractions), so it is suitable for providing high purity air.

Important features:

- automatic frost protection regulation;
- there is no need to create a condensate drain;
- with easily accessible filters (G3+F9), removable and cleanable heat exchanger;
- automatic bypass (the possibility of ventilation without heat exchange, if necessary);
- digital interface with LCD display;
- weekly and daily programmability;
- filter saturation indicator;
- WiFi connection
- SMART control (using Android / IOS application);
- night (extra quiet) mode;
- can be expanded with sensors (vapor, CO2 sensor);
- ModBus interface;
- pre- or post-heating units can be connected to it.

It is an ideal choice for those who want to implement energy-saving and extremely quiet ventilation with high energy efficiency and parameterization according to user needs, in a fully automated way while keeping the humidity of the ventilated rooms at an appropriate value.
