Horizontal duct damper

The VKK is a backdraft damper designed for installation in horizontal ducts.


Robust construction

The box is manufactured from galvanised sheet steel, ensuring that the vanes will not become deformed or loose. 


Reduced air resistance

The profiled vanes of the VKK produce a strong upward force which reduces the air resistance. 


The VKK is a backdraft damper designed for installation in horizontal ducts. The VKK box is manufactured from galvanised sheet steel. The damper inside the box is manufactured in weather-resistant and shock-proof nylon material. This robust construction ensures that the vanes will not become deformed or loose.

The profiled vanes produce a strong upward force which reduces the air resistance. This means that the vanes will also open fully at low air velocities. Air velocity should not exceed 12 m/s.
