Application

Model SMD-203 is a leakage rated smoke damper with 3V style

blades. The SMD-203 has been qualified to 2,000 fpm (10.2 m/s) and

4 in. wg (1 kPa) for operational closure in emergency smoke control

situations. Model SMD-203 may be installed vertically (with blades

running horizontally) or horizontally and is rated for airflow and leakage

in either direction.
