Pressure Drop Data SMD-201 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 sy

Application Data Damper Sleeve Dimensional Data The drawings below and corresponding table show the position of the SMD-201 damper when mounted in a factory sleeve. The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installa- tion of retaining angles and duct connections. 1 1 / 2 in. max. The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be positioned at other location
