BD-1300 Control Dampers
Installation Instructions
Applications
Since 1905, Johnson Controls has provided high
quality dampers that fit customer application and size
requirements. Continuing the legacy of application
based products, a balancing damper is now offered.
BD-1300 Balancing Dampers include:
• self-lubricating bearings
• rigid, 13-gauge frame
• 16-gauge blades
• single side linkage
BD-1300 balancing dampers are designed and built for
balancing or variable volume control only and must not
be used for tight shutoff. These dampers are intended
for manual operation but can be motorized when
required. No seals are provided.
BD-1300 dampers come in sizes that meet different
balancing application and environmental requirements.
These applications include, but are not limited to:
• volume (air) control applications, which regulate
airflow
• pressure control applications, which maintain a
constant pressure
• manual or motorized applications
• frames can be fastened together for larger sizes
IMPORTANT: BD-1300 Balancing Dampers are not
suitable for installation with the blades in a vertical
position for motorized applications.

BD-1300 series dampers may be installed with the
frame in either vertical (wall) or horizontal (floor or
ceiling) positions. The dampers may be positioned with
the blades running horizontal or vertical.

24 x 24 inch damper actually measures 23-3/4 x 23-3/4
inches.
