We pioneered nearly silent bath fan technology with the QT Series. Now we've taken it to the extreme with ULTRAGREEN™ Series Ventilation Fans that are HVI certified at less than 0.3 Sones; the quietest sound rating obtainable. ULTRA Silent™ with QStreamTM Sound Technology features a dynamically balanced DC motor and innovative airflow-smoothing baffles that reduce noise caused by turbulence. Less turbulence also means the blower turns slowly and quietly -- with no airflow loss.
