Damper And Actuator Sizing
3-V Blades - D2 and D3 Dampers
Honeywell Volume Control Dampers
feature a 3-V design that’s proven to
meet higher-level system requirements
while minimizing flow-through system loss. Blades are fabricated from
a single thickness of 16-gauge galvanized steel with three horizontal
structural V-grooves running the length of the blade.
Applications And Operation
Honeywell Volume Control Dampers are designed to control airflow
volume in medium- to high-pressure and velocity HVAC systems.
Typical applications include volume control of airflow in zoning, air
handler unit or economizer applications. Dampers are designed
to operate with a wide range of Honeywell electric and pneumatic
actuators. Operating range is from 2000 to 4000 fpm, and 2.5 to 6
inch wg. Spring return and non-spring return actuators are available
with a wide range of output torque ratings to deliver the precise
power needed for your damper application.
Certified Performance
Honeywell certifies that models D2 and D3 are licensed to bear the
AMCA Seal. The ratings shown are based on tests and procedures
performed in accordance with AMCA Publication 511 and comply with
the requirements of the AMCA Certified Ratings Programs. The AMCA
Certified Ratings Seal applies to air performance ratings only.
Durable construction details are the
cornerstone of Honeywell D1, D2 and D3
Volume Control Dampers. They feature
heavy-duty hat channel frames for
dependable operation inside ductwork.
And all models have low-profile top and
bottom frames, creating more free area
while reducing pressure loss and reducing
actuator torque.
The Right Choice
There’s a Honeywell Volume Control Damper that’s just right for your
application. The D1 airfoil extremely low leakage damper presents a
lower resistance to airflow typically used in high pressure systems.
The D2 ultra-low leakage damper keeps leakage to a minimum with
blade and jamb seals, and is designed for medium- to high-pressure
and velocity systems. The D3 low leakage damper is ruggedly built for
applications in medium pressure and velocity systems.
Blade Design
Airfoil Blades - D1 Dampers
Honeywell Airfoil Volume Control Dampers feature blades constructed
of double skin galvanized steel. This design presents a lower resistance
to airflow and has strength that is typically used in high pressure systems.

HVAC performance depends largely upon airflow, and Honeywell Volume Control Dampers are built
for both improved airflow and heavy-duty use. Honeywell has long been the leading source for airflow
control, with Volume Control Dampers that meet AMCA-certified Air Performance Standards, the highest
established standards for commercial control dampers. Designed to minimize leakage, Honeywell
dampers will give you efficient, trouble-free operation for years to come.
