Anleitung Zusammenfassung
The FSDGB-211 has been qualified to Standard GB 15931-1995 for operation and closure in emergency fire smoke situations. Model FSDGB-211 may be installed vertically (with blades running horizontal) or horizontally and is rated for airflow and leakage in either direction. Ratings Standard GB 15931-1995 Velocity: Pressure: Standard Construction Frame: Model FSDGB-211 Steel 3V Blades Qualified to Standard GB 15931-1995 Greenheck Kunshan Co. Ltd. and Greenheck Fan Corporation certifies that the model FSDGB-211 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. 10 m/s (2000 fpm) 1kPa (4 in. wg) Blades: Seals: Linkage: Axles: Bearings: Fusible Link: Size Limitations Minimum Size: Maximum Size: Single Section: Multiple Section: 127mm x 25.4 mm (5 in. x 1 in.) 1.24mm galvanized steel hat channel with reinforced corners.

Pressure Drop Data FSDGB-211 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. -«- 5D -> II «- 6D ->► P O - ll < > 1 ll l| o ^ ■ bSs* - D "\ /4 (W) (H) V 3.14 111-ll O AMCA 5.2 Pressure Drop FSDGB-211 VELOCITY VS.
