Model SMD-301V meets the requirements for smoke
dampers established by:
National Fire Protection Association
NFPA Standards 92A, 92B, 101 & 105
IBC International Building Codes
New York City
(MEA listing #260-91-M)
CSFM California State Fire Marshal
Leakage (Smoke) Damper Listing (#3230-0981:104)
Application
Model SMD-301V is a vertical blade low leakage rated smoke
damper. High strength airfoil blades insure lowest resistance to
airflow in HVAC systems with velocities to 4000 fpm (20.3m/s) and
4 in. wg (1.0 kPa).

Summary
Pressure Drop Data SMD-301V This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft 3 (1.2 kg/m 3 ). Actual pressure drop found in any HVAC system is a combi...
