Pressure drop data Fsd-311V This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All 3 3 data has been corrected to represent standard air at a density of .075 lb/ft (1.2 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 s

Transitioned damper dimensions When a combination fire smoke damper is being used in conjunction with round or oval ductwork, the FSD-311V 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. D* + 2 in. (51mm) +T s W* + 2 in. (51mm)+T s W* + 2 in. (51mm)+T s D* + 2 in. (51mm)+T s H* + 2 in.
