51CVS-SS / 51CHS-SS Stainless Steel Type C Static Fire Damper
The Alumavent 51CVS-SS/51CHS-SS is a 1-1/2 hour label static fire damper constructed in Type 304 stainless steel, UL/ULC approved for use in HVAC systems where fans automatically shut down in the event of a fire alarm. The stainless steel construction provides excellent corrosion resistance for high humidity and corrosive atmosphere applications. The Type C blade configuration positions the blades outside of the duct airflow path, and the interlocking curtain type blade design is suitable for use in fire separations with a fire resistance rating of 2 hours or less.

Additional Notes
The 51CVS-SS/51CHS-SS is UL/ULC certified for use as a 1-1/2 hour static fire damper in HVAC systems.
The 51CVS-SS/51CHS-SS is the stainless steel variant of the Type C static fire damper, designed for installation in fire-rated assemblies where corrosion resistance is required, such as commercial kitchens, laboratories, coastal facilities, and other high humidity or chemically aggressive environments. The Type C configuration locates the blades entirely outside of the duct airflow path, minimizing airflow resistance during normal system operation. The interlocking curtain blade closes under spring tension when the fusible link releases, providing a reliable passive fire barrier at duct penetrations.
