Pressure drop data SMd-302M 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 (1.201 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
