TECHNICAL
What is a sone, and how is
it measured? A sone is a
measurement of sound of how
sound is sensed. The lower
the sone value, the quieter the
listening environment. One sone
is the equivalent of a quiet
refrigerator. Broan fans feature
the quietest rating possible at
<0.3 sones as tested for HVI
certification.
What does “HVI certified” mean?
The Home Ventilating Institute
(HVI) is an independent
organization that certifies the
airflow and sound performance
of Broan products. For more
information visit www.hvi.org.
What is ENERGY STAR
®
? Refer
to the product matrix for specific
Broan fans that meet
ENERGY STAR
®
requirements.
Many of these Broan products use
high efficiency motors and lighting
to reduce energy consumption by
as much as 70%. Learn more
about ENERGY STAR
®
at
www.energystar.gov.
What does CFM mean? Cubic Feet
per Minute (CFM) is the measure
of air volume moved by the fan
blower. Choose a fan with a CFM
rating appropriate for your room
size to ensure adequate
ventilation.
What does “static pressure” mean?
Static pressure is the
measurement of airflow resistance
as it is pushed through ductwork
which reduces the effectiveness
of the fan. Learn more on the
Home Ventilating Institute website
www.hvi.org.
What is whole-house ventilation?
Whole-house ventilation provides
today’s airtight homes with a
relatively constant and controlled
lower level of ventilation. Broan
offers many virtually silent
continuous ventilation solutions
for ASHRAE 62.2 and programs
such as LEED, ENERGY STAR
®
for
Homes and CA Title 24.
OPERATION
How do I size a fan properly for my
room size and the duct run? See
the sizing guidelines on page 59
for details on proper sizing. This
section provides an explanation
and examples to help you make
the right decision.
How long should a bath fan run
after a shower is used? The Home
Ventilating Institute recommends
that a fan should be left on for
20 minutes more to clear humidity
adequately and to ensure moisture
and condensation is minimized.
How does Sensing Technology
operate? Broan has unique sensing
technology that detects humidity
or motion. Multi-speed models
automatically turn the fan speed
up when someone enters the
room or there is a rapid rise in
the humidity level from the lower
continuous CFM level. Single-
speed models turn the fan
on automatically.
How does the delay-off timer
operate? Delay-off timers
automatically shut the fan off after
a time interval set by the user.
Why do the windows and mirrors
fog even when the fan is running?
If windows and mirrors are very
cold, condensation can still form
on these surfaces. And if your
bathroom is sealed tightly,
replacement air may not be
entering the room fast enough
to displace the moist air. Fan
placement can also be a factor.
Your fan should be located far
from the replacement air source
to ensure the moist air is drawn
out first. Finally, make sure your
ductwork is as short and straight
as it can be in order to ensure
proper air outflow.
Why is water dripping from the
grille of the fan? Dripping water is
either condensation (usually due
to cold ductwork or improper duct
installation), or a problem with
the seal on a wall or roof vent.
Insulated ductwork can help solve
condensation problems, and
running the fan longer will ensure
moisture is completely removed
from the duct.
Will Broan fans work in wall-mount
applications? Refer to the product
matrix for specific Broan bath and
utility fans that may be wall
mounted.
What type of exhaust fan is best
for a sauna or hot tub area? High
CFM-rated devices are normally
recommended for this type of
application.
Can I use a fan in a steam shower?
No. Since these are normally
sealed chambers, a vacuum
will be created.
