Additional Notes
The 53CRVS is UL/ULC certified for use as a 3-hour static fire damper in HVAC systems.
The 53CRVS is designed for installation in vertical fire-rated wall and floor assemblies using round ductwork, where the HVAC system fans shut down automatically on fire alarm activation. The 3-hour fire rating makes it suitable for fire separations requiring a higher level of protection than the 1-1/2 hour 51-series dampers, including fire walls and high fire resistance rated assemblies up to 4 hours. The Type CR configuration accommodates round duct geometry while keeping the blades outside of the airflow path during normal operation. The interlocking curtain blade closes under spring tension when the fusible link releases.
