Dayton Rectangular Fire Damper

The Dayton rectangular fire damper is a static vertical unit built from 22 gauge galvanized steel. It provides a fire resistance rating of less than three hours and is designed for installation in HVAC duct systems where airflow shut-off is required during a fire event. This component suits contractors and facility managers specifying passive fire protection for commercial or industrial ventilation.

Installation orientation and duct compatibility

Verify that the ductwork runs vertically and that the opening matches the damper’s rectangular profile before ordering. Confirm the required fire resistance rating for the specific barrier meets the less than three hour classification. Ensure the surrounding construction allows proper mounting of a galvanized steel frame without modification.

Integration with fire-rated barriers

The damper fits within a fire-rated wall or floor assembly and closes automatically to maintain compartmentation. Its galvanized steel construction resists corrosion in typical HVAC environments. The static design means it operates without an actuator, freeing up control wiring and power supply considerations in the build.

Questions about this item

What comes with the Dayton fire damper and what must be purchased separately?

The damper itself is made of 22 ga galvanised steel. Mounting hardware, duct connectors and any required access doors are not included and must be sourced separately.

Which version of this static vertical damper should I choose for my duct opening?

Select the model that matches your exact duct width and height; the fire-resistance rating is less than three hours for all listed sizes.

What does the "less than 3 hour" fire rating mean once the damper is installed?

In a fire test the assembly will maintain integrity for up to three hours, giving the building’s fire barriers time to contain flames and smoke.
