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. Model DFDAF-330 may be installed
vertically (with blades running horizontal) or horizontally and is
rated for airflow in either directions.
This model has a manual quadrant which allows the DFDAF-330
to function as both a fire damper and a manual balancing
damper.

Sleeve and Sideplate Dimensions
The drawings below and corresponding table show the position of the DFDAF-330 damper when mounted in a factory sleeve ("A"
dimension). The standard mounting locations provide enough space for the mounting of manual quadrant(s) and allow space for
installation of retaining angles and duct connections. The following options may affect the range of available mounting locations:
transitions, security bars, grille tabs.
The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be positioned at
other locations within a range of 7 3/,6 in. (183mm) to 16 in. (406mm) for the "A" dimension.

Transitioned Damper Dimensions
When a fire damper is being used in conjunction with round or oval ductwork, the DFDAF-330 can be supplied in a factory sleeve
with round or oval transitions on both ends of the sleeve. Dampers should be ordered to the duct dimensions. Drawings below show
overall damper size.
