Product Description
The Aldes CAR3 Constant Airflow Regulator is a pressure
independent balancing damper that automatically regulates
airow in duct systems to constant levels. The CAR3 requires
no electric or pneumatic power or sensors, and works solely o
system pressure.
Unlike traditional manual dampers, the CAR3 compensates
for changes in duct pressure caused by stack eect, operable
windows and doors, wind, loading lters, etc. The CAR3 provides
a low-cost solution to maintaining the correct airow balance of
ventilation systems, improving system performance and indoor
air quality, which can provide significant savings on annual
operating costs.
Key Features
• Dual-side airow adjustment dial and CFM indicator allows
you to set or change the airow quickly, in supply or exhaust
applications, without removing the CAR3 from the duct.
• Modulating rotary damper automatically responds to
changes in duct pressure to maintain set ow.
• Resin is enhanced with antimicrobial, anti-static, and ame
retardant additives for increased safety and durability.

CONSTANT AIRFLOW REGULATOR
Construction
• CAR3 constructed of amorphous thermoplastic resin
enhanced with antimicrobial, anti-static, and ame retardant
additives to improve material performance, reduce need for
maintenance, and increase safety.
• CAR3 is UL 2043 safety classied and labeled for ame and
smoke generation (File No. R39897).
• Double lip gasket around the circumference ensures a tight,
no-leak t.
Maintenance
The CAR3 needs no maintenance when used in normal
conditions. The addition of antimicrobial and anti-static
additives in the material increases the longevity and reliability
of the CAR3. There is no risk of dust deposit or obstruction
because the CAR3 has no airways subject to clogging. If the
intended application includes air heavily loaded with dust or
grease, access to the CAR3 will be possible through the terminal
device or with an access panel or door.
Warranty
Guaranteed for 7 years, from date of shipment, against all
defects in material or workmanship, provided that the material
has been installed and used under normal conditions. This
warranty is limited to the repair or replacement of the material.
APPLICATIONS
• Automatic balancing of round duct.
• Balance supply or exhaust/return duct in high-rise
building.
• Sized to t inside standard rigid round ducting,
take-os, tees, and more.
• New construction or retrot.

How to Specify Aldes: CAR3
Step 1: Reference the model code below and performance details within this specications sheet to select the appropriate CAR3.
Step 2: Determine the required PRESSURE RANGE for the CAR3 based on the anticipated external static pressure of the system at
the installed CAR3 location.
NOTE: The CAR3-L (low-pressure) is designed for systems with pressures between 0.12 and 1.2 in. w.g. (30 to 300 Pa), and
CAR3-H (high-pressure) between 0.4 and 2.8 in. w.g. (100 to 700 Pa).
Step 3: Select the desired AIRFLOW RANGE.
NOTE: Ranges available: 4, 5, or 6. Each has a unique range for both low- and high-pressure variants.
See Airow Settings and Performance Data for additional details. Factory calibration of the CAR3 is available on request.
Step 4: Select the ROUND DUCT SIZE.
NOTE: This number cannot be less than the AIRFLOW RANGE: i.e. an airow range of 5 requires a duct size of 5 or 6
inches, R5 or R6 respectively.

4. MAINTENANCE & WARRANTY
• The CAR3 needs no maintenance when used in normal conditions. The addition of antimicrobial and
anti-static additives in the material increases the longevity and reliability of the CAR3. There is no risk
of dust deposit or obstruction because the CAR3 has no airways subject to clogging. If the intended
application includes air heavily loaded with dust or grease, access to the CAR3 should be possible
through the terminal device or with an access panel or door.
• ALDES Ventilation Corporation warrants the CAR3 to be free from manufacturing defects and
guarantees the performance within specied limits for a period of seven (7) years when installed in
normal environmental air systems for general residential and commercial heating, ventilating and air
conditioning. This warranty does not include installation in industrial applications or caustic, noxious
or otherwise hazardous airhandling equipment. This warranty is limited to replacement of the product
only and does not extend to consequential claims.

Product Description
Aldes High-Performance Wall Hoods are designed for use in
exhaust or supply ventilation systems and fresh air kits. They
are engineered to accommodate high airow pressure and
velocities found in premium fan and dryer vent systems. Wall
hoods are available as screened or dampered versions. Each
wall hood is designed to maximize airow and minimize noise.
Construction
Wall Hoods are available in heavy-gauge G90 galvanized
steel.
Screened Wall Hoods
1/4” galvanized steel mesh. Suitable for use in exhaust or
supply ventilation systems and fresh-air kits.
Dampered Wall Hoods
For use in exhaust ventilation and dryer venting systems. A
magnetic-catch damper ensures a tight closure when the fan is
not running and eliminates damper utter in windy conditions.
These hoods should be used when backdraft dampers are not
present at other locations within the duct system.

Product Description
Ventergy® Series Ventilator Fans represent years of engineering
development to combine the energy eciency and sound performance
of a forward-curved fan with the durability and pressure characteristics
of a backward-inclined impeller fan.
BVS Series Blending Ventilators are highly versatile, continuous-duty
ratedunitsforresidentialapplications.Theymeet ENERGYSTAReciency
criteria for low energy consumption. The BVS is designed to provide
fresh outdoor air and blend it with indoor air drawn from bedrooms or
areas typically not served by a central thermostat before ltering and
distributingthis airto themain living areasofthe home.Thermalcomfort
isenhancedbecausewarmer airis drawnnaturallyfromthe heatedliving
areas to the cooler bedrooms.
The BVS is designed to lter both indoor and incoming fresh air and
prevent the introduction of contaminants as a result of unwanted
infiltration through leaks in the building’s envelope. By slightly
pressurizing the structure, the BVS also reduces the risk of backdrafting
heatingappliances,waterheaters,andreplaces.Quiet,continuous-duty,
energy-ecient,external-rotormotorswithpermanentlysealedbearings
provide many years of maintenance-free performance.
Construction
BVS series fans are constructed of heavy-gauge galvanized steel to
prevent corrosion caused by moisture. The cabinet is internally lined
withacoustic, closed-cell foaminsulation that acts as a vaporbarrier.This
allowsforinstallationdirectly aboveliving spacesor inunheatedplenum
spaces without concern for noise or condensation. Duct connecting
collars may be relocated on the fan intake manifold to accommodate
dierent installation requirements.
Fan Controls
The fan can be operated manually or automatically by a programmable
timer, dehumidistat, or other appropriate electronic switch device. The
fan may also be operated in conjunction with a variable speed control.

Fan and Motor
The fan motor is an energy-ecient, permanent-split-capacitor type
of external-rotor design. Totally sealed to protect against moisture and
contaminants,itincorporatespermanentlylubricatedandsealedbearings
and automatic-reset thermal-overload protection. It is designed and
certied for continuous duty or intermittent operation.
The fan uses a backward-inclined impeller design that minimizes dust
collection on blades. Each fan is statically and dynamically balanced at
the factory to eliminate vibration and ensure quiet operation.The entire
motorandfan assemblyismountedon adrop-downhinged accesspanel
for simple service and inspection, and it can be removed from the fan
without disassembling the duct connections.
Filters
Each BVS comes standard with a disposable-type 1”pleated MERV 8 lter
to comply with ASHRAE 62.2 and ENERGY STAR standards. Permanent,
washable, electrostatic-type lters are also available.
Locating and Installing
The compact dimensions and versatile mounting options permit
installation above drop ceilings, between ceiling joists, or within a small
sot location. They can be installed horizontally or vertically.

MAINTENANCE
Monthly: Clean the exhaust and supply grilles.
Seasonally: Clean the fresh air intake wall hood.
Ducting the Fan
Theducting fromthis fanto theoutside ofthe buildinghas astrong eect
ontheairow,noiseandenergyuseofthe fan.Usetheshortest,straightest
duct routing possible for best performance, and avoid installing the fan
with smaller ducts than recommended. Insulation around the ducts can
reduce energy loss and inhibit mold growth. Fans installed with existing
ducts may not achieve their rated airow.
Use ductwork of a diameter that is the same as or greater than the
diameter of the duct connectors on the fan.
Performance
Fan airow and energy performance are tested in accordance with HVI
procedures.
