Application

Model SMD-M201 is a leakage rated smoke damper with 3V style
blades. The SMD-M201 has been qualified to 10.2 m/s and 1 kPa
for operational closure in emergency smoke control situations.
Model SMD-M201 may be installed vertically (with blades running
horizontally) or horizontally and is rated for airflow and leakage in
either direction.

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 1.201 kg/m

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.

AMCA Test Figures

Figure 5.3 Illustrates a fully ducted damper. This configuration has the lowest pressure drop of the three test configurations

because entrance and exit losses are minimized by straight duct runs upstream and downstream of the damper.

Figure 5.2 Illustrates a ducted damper exhausting air into an open area. This configuration has a lower pressure drop than
Figure 5.5 because entrance losses are minimized by a straight duct run upstream of the damper.

Figure 5.5 Illustrates a plenum mounted damper. This configuration has the highest pressure drop because of extremely high
entrance and exit losses due to the sudden changes of area in the system.
