ApplicationThe FD-140 fire damper employs triple-V blades for point-of-origin control of fire in static and dynamic HVAC systems. TheFD-140 is qualified to 4,000 ft/min (20.3 m/s) and 6 in.wg. (1.5 kPa)and may be installed in vertical walls or partitions, or horizontallyin floors or assemblies with fire resistance ratings up to 2 hours.

Pressure drop testing was performedin accordance with AMCA Standard500-D using the three configurationsshown. All data has been corrected torepresent air density of 0.075 lb/ft.Actual pressure drop in any ductedHVAC system is a combination ofmany elements. This information,along with analysis of other systeminfluences, should be used toestimate actual pressure losses for adamper installed in a given HVACsystem.

Figure 5.3 — Ducted Inlet and Outlet Figure 5.2 — Ducted Inlet Figure 5.5 Plenum Mount

Ducted Inlet and OutletAMCA Figure 5.3 Illustrates a fully ducteddamper. This configuration represents thelowest pressure drop of the three testconfigurations because entrance and exitlosses are minimized by straight duct runsupstream and downstream of the damper.

Ducted InletAMCA Figure 5.2 Illustrates a ducteddamper exhausting air into an open area.This configuration has a lower pressuredrop than Figure 5.5 because entrancelosses are minimized by a straight duct runupstream of the damper.

Plenum MountAMCA Figure 5.5 Illustrates a plenummounted damper. This configuration hasthe highest pressure drop because ofextremely high entrance and exit lossesdue to the sudden changes of area in thesystem.

NOTE: 1. The entire damper frame is not required to be installed within the wall, partitionor floor. However, the closed plane of the damper blades must be inside the wall, partition or floor.

Typical Damper Dimensional DataThe drawings and corresponding table show the position of the damper when mounted in afactory sleeve. The standard mounting locations provide enough space for installation ofretaining angles and duct connections.
