The very name of the WHISPER AIR heat recovery unit speaks for itself. Its operation at nominal flow is almost inaudible, the noise level of 35 dB (A) which is comparable to a whisper and for classroom and office applications this is essential. The heat recovery unit is equipped with energy-saving EC motors and a highly efficient heat recovery unit exchanger, either in a standard aluminum core or enthalpy core to prevent the drying of indoor air.

The unit is controlled by AirGENIO controls allowing the user to customize preferences for all climate conditions ensuring a comfortable environment for all. Optimum CO2 levels in the air are maintained by an integrated CO2 sensor that controls the ventilation rate.

WHISPER AIR is specially designed for the ventilation of schools, kindergartens, offices, open-space and conference rooms.
