Type A Curtain Blade Fire Dampers

ASX Type A curtain fire dampers are UL and ULC listed for installation in walls, floors and partitions with a fire rating of 1-1/2 or 3 hours.  The type A fire damper is constructed with the damper framed the same size as the duct size and includes the blade stack and edge seals within the air stream.  Typical installation is in a low pressure (less than 3" w.c.) system

Fire dampers for use in static systems are used in duct systems and penetrations where there is little to no airflow when the damper closes.  ASX Type A static curtain fire dampers may be installed vertically or horizontally in static HVAC systems that automatically shut down in the event of a fire.

Fire dampers for use in dynamic system are required if the HVAC systems will be operating with the fans on during a fire incident.  Dynamic system dampers are expected to be able to close against the air velocity and pressure produced by the system fan.  ASX Type A dynamic curtain fire dampers may be installed vertically or horizontally in dynamic HVAC systems that continue to run in the event of a fire.
