Model CFR is Designed for
QUIET
, EFFICIENT COMFORT
Model CFR fan terminals are specif-
ically designed for quiet operation.
They also offer improved space com-
fort and flexibility for a wide variety
of HVAC systems. This is critical in
today’s buildings, where
occupants are placing more empha-
sis on indoor acoustics.
Occupant-Sensitive Design
Due to heightened interest in
Indoor Air Quality, many HVAC
system designers are focusing on
the effects of particulate contam-
ination within a building’s occupied
space. Often, HVAC system noise
is overlooked as a source of occu-
pied space contamination. The CFR
terminal is specifically designed
to eliminate obtrusive fan noise from
reaching the occupants, while pro-
viding constant air motion in the
space.
Occupants will benefit from the CFR
design that minimizes low fre-
quency (125Hz-250Hz) sound levels
that typically dominate the space
sound level. The CFR also minimizes
the fluctuation in sound levels that
occur during VAV damper modu-
lation.
For the Building Designer:
FLEXIBILITY
Selection and Layout. The CFR pro-
vides flexibility in system design.
Reduced noise at the fan terminal
allows the system designer to place
properly sized units directly above
occupied spaces. It is not neces-
sary to use the crowded space
above a hall or corridor to locate
the equipment. This will reduce
lengthy and expensive discharge
duct runs. The standard shallow cas-
ing height (14" up to 1000 CFM)
minimizes conflict with other sys-
tems competing for ceiling space.
The FlowStar
TM
sensor ensures accu-
rate control, even when space
constraints do not permit long
straight inlet duct runs to the ter-
minal.
Sizes. Model CFR terminals are
available in nine fan sizes to han-
dle airflow capacities between 100
and 4800 CFM. Most fan sizes are
available with three primary air valve
sizes to optimize the unit fan and
primary air valve combinations
required by current industry needs.
