    Transfer grille

    noise attenuated for internal use

BluMartin has designed a new noise attenuated transfer grille, freeAir zero, which allows passive airflow between rooms. With noise attenuation of 33dB, it powerfully reduces cross talk as much as possible.

The unit looks the same as the cascade fan freeAir Plus, but has got no active elements.
