t Application and Design
The Model ESYA is a UL/ULC listed and labeled Class I
leakage rated Smoke Damper. Blades are of the airfoil
shaped design for low pressure loss. The damper is
approved for airflow in either direction and provides a
maximum leakage of 8 cfm/sq. ft. at 4” w.c. s.p. It has
been designed to be installed in a vertical or horizontal
mounting position in the ductwork or a separate sleeve
within 24” of the smoke partition. These dampers are
approved for use in engineered smoke control systems
and are controlled via smoke detection system. Electric
(24v, 120v and 230v) or pneumatic actuators are used to
operate the smoke dampers.
Standard Construction:
Frame: roll formed galvanized steel hat-section with
staked corners and integral bracing
Blades: airfoil-shaped, double skin galvanized steel of
roll formed construction, min. width 5”, max. width 7”
Bearings: bronze oilite, press-fit into frame
Axles: square, plated steel
Seals: pressure sensitive 450°F silicone blade edge
seals and flexible metal jamb seals
Linkage: concealed in frame, linkage bars are .125”
Designed and tested in accordance to standards: UL 555S, ULC
S112.1. Labeled and listed by UL/ULC under File # R26359.
They meet all the NFPA 90A, IBC Code and other major code
requirements for Smoke Dampers.

Notes:
• Non-sleeved dampers with side plate are furnished
approximately 1/4” smaller than given duct dimensions.
Sleeved dampers are furnished approximately same
size as given duct dimensions, unless otherwise noted.
