Greenheck Fan Corporation certifies that the model DFD-210 shown herein is licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 511 and comply with the requirements of the AMCA Certified Ratings Programs. The AMCA Certified Ratings Seal applies to air performance ratings only.
Space Envelopes
The drawings below and corresponding table show the position of the DFD-210
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 3⁄16 in. (183mm) to 16 in. (406mm) for the “A” dimension.
| in. (mm) | “A” Dimension |
|---|---|
| Sleeve Std | Sleeve Max |
| Dampers with no OCI | 7 3⁄16 in. (183) |
| Height <11 in. (279) with OCI | 12 (305) |
| Height > 11 in. (279) with OCI | 7 3⁄16 in. (183) |
NOTE: Entire damper frame is not required to be installed within the wall. The damper blades, when closed should be contained within the wall.
Transitioned Damper Dimensions
When a fire damper is being used in conjunction with round or oval ductwork, the DFD-210 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.
*These
dimensions are furnished approximately ¼ in. (6mm) undersize, except round and
oval dimensions which are approximately 1⁄8 in.(3mm) undersize. Ts =
(2)(Sleeve Thickness)
Multiple Section Dampers
Dampers larger than maximum single section size are supplied as a factory assembly of two or more sections of equal size. The following figures show maximum damper section size and assembly configurations for multi-section dampers
