Rectangular Fire Damper 11-3/4x15-3/4 In
This Dayton fire damper is a rectangular HVAC control device designed for installation in ductwork. It is intended for use in low-pressure HVAC systems where fire protection is required. The unit suits commercial and industrial building projects needing code-compliant fire containment.
22-Gauge Galvanized Steel Static Mount
The damper body is constructed from 22-gauge galvanized steel for corrosion resistance and structural rigidity. It is configured for static mounting in a horizontal orientation with nominal duct dimensions of 16 inches wide by 12 inches high. A retaining angle is recommended for secure installation.
1-1/2 Hour Fire Rating 165-Degree Fusible Link
This model carries a fire rating of 1-1/2 hours and meets standards including UL 555, NFPA 80, 90A and 101, IBC, CSFM and NYC MEA. The fusible link activates at 165 degrees Fahrenheit to close the damper automatically during a fire event. Free area measures .901 square feet, which limits airflow capacity compared to larger damper sizes. Buyers needing greater free area for high-volume systems should consider larger models.
