We pioneered nearly silent bath fan technology with the QT Series. Now we’ve taken it to the extreme with ULTRA™ Series Ventilation Fans featuring ULTRA Silent™ Sound Technology that are HVI certifi ed at <0.3 Sone; the quietest sound rating obtainable.
In the ULTRA™ Series, sound takes another sabbatical with a quiet, dynamically balanced DC motor mounted behind the wheel, a state-of-the-art blower design that reduces turbulence, and a free-flowing 6" duct outlet opening that won’t inhibit airflow and thus create unnecessary noise.


All ULTRATM series fans and fan/lights are Energy Star qualified. With ULTRA GreenTM Energy Saving DC Motors, they are actually almost 10 times more efficient than Energy Star requirements.
