t Application and Design

The Model ESWA is a UL/ULC listed and labeled Class
I leakage rated Smoke Damper. Blades are of the 3V
shaped or crimped design. 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: 5” roll formed galvanized steel hat-section with

staked corners and integral bracing
Blades: 16 ga. roll formed, galvanized steel, 3V blade
design, min. width 4.250”, max. width 7.250”

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.
