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 certified at less than 0.3 Sones; 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 freeflowing 6" duct outlet opening that won't inhibit airflow and thus create unnecessary noise.
