Application
Model SMD-301V meets the requirements for smoke 
Model SMD-301V is a vertical blade low leakage rated smoke dampers established by:
damper. High strength airfoil blades insure lowest resistance to

                        Pressure Drop Data SMD-301V 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  sys

                          Transitioned Damper Dimensions When a fire/smoke damper is being used in conjunction with round or oval ductwork, the SMD-301V 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.
