Model OFSD-212 APPLICATION Out Of Wall Combination FIRE SMOKE DAMPERS Model OFSD-212 is an ‘out of the wall’ high performance combination fire smoke damper with 3V style blades. OFSD-212 is approved for use in walls, partitions, and floors with fire resistance ratings less than 3 hours. Removal of wall grille allows access to actuator and other components. This model's operational ratings of 2000 fpm (10.2 m/s) and pressures to 4 in. wg (1 kPa). OFSD-212 shall be installed vertically (with blades running horizontal) or horizontally and is rated for airflow and leakage in either direction.

All data has been corrected to represent standard air at a density of .075 lb/ft (1.201 kg/m ). 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. 5D 6D 5D 6D Figure 5.3 5D Figure 5.3 Figure 5.3 6D 5D 4 (W) (H) 3.14 D= Figure 5.2 5D 5D Figure 5.2 Figure 5.2 Figure 5. 5 Figure 5.5 Figure 5. 5 D= D 4 (W) (H) 3.14 4 (W) (H) 3.14 Figure 5.3 AMCA 5.2 Pressure Drop OFSD-212 5D 4 (W) (H) 3.14 D= Figure 5.2 Figure 5. 5 * This size is based on multi-section unit. 12 in. x 12 in.

(1.5mm or 1mm) Wall Opening Sizing To accommodate for sleeve and thermal blanket thickness, the wall opening must be oversized by 3⁄8 in. (9.5mm) as shown. For example, if the nominal damper size required is 18 in. x 14 in. (457mm x 356mm), the wall opening size needs to be 18 3⁄8 in. x 14 3⁄8 in. (467mm x 365mm). The damper itself is undersized 1⁄4 in. (6mm) on each dimension for an actual damper size of 17 3⁄4 in. x 13 3⁄4 in. (451mm x 349mm). This is also the inside dimensions of the sleeve (for grille considerations).
