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.

Page 2: Pressure Drop Data
Pressure Drop Data This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft Actual pressure drop found in any HVAC system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVAC system. - Page 3 0.49 1.16 4000 0.64 Greenheck Fan Corporation certifies that the model SMD-202 shown herein is licensed to bear the AMCA Seal.
