Fire, Smoke & Ceiling Radiation Dampers
Selecting a Fire Damper
Fire dampers are used to prevent the transmission of flames through air ducts and in air transfer openings in
walls and partitions. Fire damper construction is available in Type A, Type B and Type C, as well as for use
in static systems or dynamic systems.
Type A, Type B and Type C Dampers:
Fire dampers are constructed to meet the UL555 test as to minimum construction gauge and edge seals and
are manufactured in three types (Type A, Type B and Type C).
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. The Type A fire damper has the highest air pressure
drop. Typical installation is in a low pressure (less than 3” w.c.) system.
The Type B fire damper has the blade stack out of the airstream, but the receiving channel is within the
airstream. Air pressure drop is substantially reduced. The Type B fire damper is generally used where the
duct height is 12” or less, or where air speed velocities are fast enough.
The Type C fire damper has a 100% free area through the damper for a minimal pressure drop, and can be
used in a low, medium or high pressure application.
Fire Dampers for Static Systems and Dynamic Systems
:
Fire dampers for use in static systems are used in duct systems or penetrations where there is little to no airflow when the damper closes. Fire dampers for use in dynamic systems are required if the HVAC system 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.
In most cases, static system dampers rely on gravity to pull the curtain/blade closed, and dynamic system
dampers utilize springs to pull the curtain closed. Both static and dynamic fire dampers carry an hourly fire
resistance rating (1-1/2 or 3 hours). Dynamic system dampers are also provided with an airflow rating,
indicating the maximum velocity and static pressure that the damper is designed for
