Product Overview
Reduce sound levels and improve sound
quality in real-world installations.
The innovative, patent-pending
QStream™ technology utilizes
airflow-smoothing baes that
reduce turbulence which means
the blower can turn more slowly
and quietly—without airflow loss.

Damper Technology
Patent-pending QFlow technology removes the duct damper flap from the
airstream path, reducing static pressure and noise when the fan is on. It also
helps achieve desired building airtightness scores when the fan is o.

Without QFlow, outdoor
air can intrude past the
damper edges.
Without QFlow, the flap
impedes airflow which
increases static pressure,
turbulence and noise.
With QFlow, outdoor air
intrusion is blocked with the
new edge-to-edge design.
With QFlow, the flap
lifts out of the way,
minimizing turbulence for
more quiet operation.
