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 blade axis.
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.
For damper (Fig. 10) the open damper blade overlaps the damper body from dimension D=315
by the value “a” or “a” and “c”. These values are specified in the Tab. 3.2.1.
Values "a" and "c" has to be respected when projecting related smoke exhaust ducts.
