Smoke extraction dampers single are designed to remove heat and combustion products (e.g.
smoke) from single fire compartment according EN1366-9.
Smoke extraction dampers single are designed for installation with horizontal or vertical axis of the blades.
Backtoback smoke exhaust duct has to be hung or supported so as all load transfer from the backtoback
smoke
exhaust
duct
to
the
damper
is
absolutely
excluded.
To
provide
needed
access space to the control device, all other objects must be situated at least 350 mm from the
control parts of the damper.
During installation the damper blade must be in position CLOSED. The damper body should
not be deformed in the course of installation. Once the damper built in, its blade should not grind
on the damper body during opening or closing.
Example, how to calculate effective area and size of SEDS-L damper [AxB], when knowing air volume in [m
³
/s] or [m
³
/h] on damper.
Maximum allowed air velocity on SEDS-L is 12 [m/s].
Formula:
Q … air volume [m
³
/s]
Sef … effective free area of damper [m
²
]
v … air velocity on damper [m/s]
Example:
Air volume needed is 26000 m
³
/h
26000 / 3600 = 7,222 m
³
/s
7,222 / 12 = 0,602 m
²
is min. effective free area [Sef]
Find the value Sef in the table 3.2.1. The effective are has to be the same or bigger. There will be more options of damper, sizes AxB.
