Application
Model SMD-202 is a leakage rated smoke damper with 3V style 
blades. The SMD-202 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-202 may be installed vertically (with blades 
running horizontally) or horizontally and is rated for airflow and leakage 
in either direction.
