"ERV" version: with an enthalpy system heat exchanger, automatic 100% bypass function (the possibility of ventilation without heat exchange) ensures the highest energy efficiency ventilation while keeping the humidity at the right level.

A device with a Passive House certificate that meets the strictest requirements of energy-saving ventilation systems. Accordingly, it is one of the products with the highest thermal energy recovery ("A+" energy efficiency class) central ventilation device.

Suitable for energy-saving, dust- and other pollutant-free ventilation of individual rooms in family houses, apartments, and offices, max. In the case of a floor area of ​​100 square meters.
The internal structure of the device is made with EPP (expanded polypropylene) insulation, for high airtightness and thermal insulation properties.

Its energy-saving EC motor and maintenance-free rolling bearings designed for a long service life enable low-noise operation.

The unit's radial fans with forward bending blades are direct driven and dynamically balanced for quiet and vibration-free operation.

The highly efficient, mold- and bacteria-free membrane heat exchanger unit with an enthalpy system ensures outstanding thermal efficiency in its category (max. 95%), as well as adequate management of humidity. The built-in polymer membrane made with antibacterial technology is mold and bacteria-free, and also prevents the passage of pollutants in the air and eliminates odors.
The device has G4 filters that can be easily accessed without tools, can be cleaned and replaced if needed.
