APPLICATION
Model FSD-211 is a combination fire smoke damper with 3V style
blades. The FSD-211 has been qualified to 2000 fpm (10.2 m/s) and
4 in. wg (1 kPa) for operation and dynamic closure in emergency fire
smoke situations. Model FSD-211 may be installed vertically (with
blades running horizontal) 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 .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.

(1.201 kg/m3).
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.
