Square Fire Damper for HVAC Systems

This Dayton square fire damper fits nominal 10 in. by 10 in. ducts and installs in vertical or horizontal orientations. It is built from 22 ga. galvanized steel and carries a 1-1/2 hour fire rating. The dynamic design suits low-pressure HVAC systems in commercial and institutional buildings.

Fusible Link Activates at 165 Degrees F

The damper releases automatically when the fusible link reaches 165 degrees F, closing the opening to limit fire spread. This single temperature rating determines whether the unit matches the fire-protection plan for the space. Verify the required link temperature before specifying.

Mounts With Retaining Angle 2TGG7

Installation uses the recommended retaining angle 2TGG7 to secure the 3-11/16 in. deep frame within the duct opening. The assembly provides 0.422 sq. ft. of free area for airflow when open. Compliance includes UL 555, NFPA 80, 90A, 101, IBC, CSFM and NYC MEA standards.
