DESCRIPTION
Shahrokhi fire dampers contructed in three
types of corrugate , parallel and opposite.These dampers have an access door to
control and change the fuse (Figure 5) and
either equipped with a command system to
close the air duct path as following:

CORRUGATE FIRE DAMPERS
The corrugate fire dampers have a number
of interlocking blades which these blades
fixed the damper at open position by use a
support.In fire time at vertical fixing position the
damper closed because of blades weight
and at horizontal fixing position closed by a
special spring (figure 6).
Either in these type of dampers is possible to
fix the blades out side the air path inside a
casing to decrease air pressure drop
(figure 7).

PARALLEL & OPPOSITE FIRE DAMPERS
The parallel and opposite fire dampers have
multy blades with a common linkage
mechanism which these blades fixed
damper at open position by use a support.In fire time , the damper closed because of
the weight attached the blades at vertical
fixing position (Figure 8).
Either is possible to connected the linkage
mechanism to an electrical motor at
horizontal and vertical fixing positions
(Figure 9).
