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/m3.
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.

Standard 500-D.
Damper blades shall be 1.5mm galvanized steel 3V type with three longi-
tudinal grooves for reinforcement. Blades shall be completely symmetrical
relative to their axle pivot point, presenting identical resistance to airflow
and operation in either direction through the damper (blades that are nonsymmetrical relative to their axle pivot point or utilize blade stops larger
than 13mm are unacceptable).
Damper frame shall be 1.5mm galvanized steel formed into a structural hat
channel shape with reinforced corners. Bearings shall be sintered bronze
