Fire Dampers are intended for use where air ducts penetrate or terminate at openings in walls or partitions, in air transfer openings in partitions, and where air ducts extend through floors as specified in the Standard for Installation of Air Conditioning and Ventilating Systems, NFPA 90A. In a Fire Emergency the Fire Damper is designed to close and prevent the spread of fire from one side of the wall or partition to the other.
Fire Dampers are evacuated for use as either:
a) Fire Dampers for Static Systems: For HVAC Systems that are automatically shut down in the event of a fire.
b) Fire Dampers for Dynamic Systems: For HVAC Systems that are operational in the event of a fire.
c) Combination Fire and Smoke Dampers: For locations in HVAC systems where a Fire Damper and a Smoke Damper are required at a single location.
DVAC FIRE DAMPERS ARE UL 555 CLASSIFIED – 3 HOUR RATING
