ENERGY STAR

fans use 70% less energy, on average, than standard models and may qualify for local utility rebates
ULTRASMART
™
DC MOTOR AND CONTROL
TECHNOLOGY
To virtually ensure full-rated performance—
regardless of the ducting situation—ULTRA
™
Green
Series fans automatically monitor and adjust CFM
output. For continuous ventilation needs, multi-
speed models may be precisely set as low as 30
CFM to avoid costly over-ventilating. A second
dial controls runtime at maximum CFM. Our DC
motor is the most efficient in our line—80 CFM
models use only 5.8 watts.
ULTRASILENT
™
SOUND TECHNOLOGY
ULTRA
™
Green Series Ventilation Fans are HVI
certified at a remarkable <0.3 Sones; the quietest
sound rating obtainable. A dynamically balanced
DC motor mounted behind the wheel, a state-
of-the-art blower that reduces turbulence, and
a free-flowing 6" duct outlet opening that won’t
inhibit airflow make it possible. There’s no quieter
fan available.
POWERFUL
MOTION & SENSING
TECHNOLOGIES
ULTRA Fans with Sensaire humidity sensing
technology detect the rapid rise in humidity at
the ceiling level. This means that they will react
to shower humidity much faster than competitive
fans or wall controls. Multi-speed models turn
the fan speed up from the lower continuous
CFM level. Single-speed models turn the fan on
automatically.
ULTRA Fans with motion sensing and multi-
speed capability automatically turn the fan up
to maximum speed from the lower continuous
setting when motion is detected which is ideal
for family members who forget to turn the fan on.
* Compared to a central fan-integrated system when used for continuous ventilation; based on software calculations
and analysis conducted by Broan-NuTone.
