To determine leakage at static pressure differentials higher than 1 inch water gage, multiply leakage at 1 inch (determined from the Damper Leakage Table) by correction factor for higher static pressure (determined from the Correction Factor Table).

Leakage ratings are based on AMCA Standard 500 using Test Setup Apparatus Figure 5.5. Torque applied holding damper closed at 10 lb·in./sq. ft (0.1216 kPa) of damper with minimum of 20 lb·in (2.26 N·m).

Dampers may tolerate higher pressures and velocities than those listed here. Conservative ratings are presented intentionally in an effort to avoid misapplication. Consult Johnson Controls when damper is to be applied in conditions exceeding recommended maximums.

Note: Leakage information based on pressure differential of 1 inch w.g. (0.25 kPa).
Note: Performance curves are based on AMCA Standard 500 using test setup apparatus figure 5.3 (damper installed with duct upstream and downstream). Static pressure and cfm (lps) are corrected to 0.075 lb/cubic ft (1.2 kg/cubic meter) air density.
