Greenheck DFDAF-330 Installation instructions
Model DFDAF-330
Application
Model DFDAF-330 is a multi-blade fire damper with airfoil style
blades for use in walls, floors, and partitions with fire resistance
rating of 3 hours or more. The DFDAF-330 is qualified to 4,000
fpm (20.3 m/s) and 8 in. wg (2 kPa) for dynamic closure in
emergency fire situations. Model DFDAF-330 may be installed
vertically or horizontally (with blades running horizontal) and is
rated for airflow in either directions.

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/ft3(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.
