Dayton 15-5/8 in Fire/Smoke Damper

This round fire and smoke damper carries a Class II leakage rating and operates on 24V AC power. It fits a nominal 6 in duct with an overall diameter of 5.9 in and a rough opening width of 6 in. The single-panel design uses galvanized steel blades within a 20 ga frame.

Dynamic Operation at 3000 fpm

Rated for dynamic operation, the damper handles maximum air velocity of 3000 fpm and maximum air pressure of 4 in wg. These limits define sustained airflow performance rather than a brief surge. The square rough opening measures 16 in by 15.7 in for secure mounting in square ductwork.

Replaces Worn or Non-Compliant Dampers

This unit replaces an existing fire/smoke damper that no longer meets leakage or actuation requirements. The upgrade is worth it when the current damper fails testing, shows corrosion on the galvanized steel blades, or lacks the 24V AC actuator needed for modern control systems.
