KLM dampers are the most applied balancing dampers to regulate the required airflow. These dampers are equipped with a turning blade, adjustable from 0 – 90° (90° is closed). A certain flow of air will always leak through even when the blade is closed. The KLM damper has a turning, circular blade. The blade is stepless adjustable 0-90°. The damper is used in cases of lower demands for shut-off capacity. The damper admits an insulation thickness of approx. 50 mm. In appropriate cases the damper can be used for regulation.

Shut-off damper DSU
l indab | dampers and measure units
DescriptionHas a turning, circular blade. The blade is stepless adjustable 0–90°. The damper is used when you have lower demands for shut-off capacity. The damper admits an insulation thick-ness of approx. 50 mm.
The damper can on occations be used for regulation.
Setting angle α α = 0° = open blade, α = 90° = closed blade
There is a separate assembly, measuring, balancing and maintenance instruction for this product.
Ø 63–1000 fullfills pressure class A in closed position.
The cup at Ø 80–630 can be complemented with the special insulation cup IK at insulation thicker than 50 mm.
