What it is and does:
With Inno dampers you absorb disturbing noise from round air ducts. You can install an Inno dampers in an air duct in one go without installation costs. The Inno damper is made in such a way that it fits firmly in the air duct after pressing gently and does not shift.

The noise reduction can be further increased by placing several dampers in succession. The Inno dampers also have a small opening that can be used to measure the pressure difference across the damper. Inno dampers are available in different diameters. 

Inno dampers can be used in applications such as a crosstalk damper and as a damper for the (often) annoying noise from ventilation systems, such as a heat recovery unit, in homes (particularly recently completed new-build homes in which good ventilation is required). Users can make their living environment considerably quieter with a small investment. Inno dampers can also be used in round air ducts in boats to, for example, muffle sound from the engine compartment to the outside. The product deals with the sound as close to the source as possible.

Inno dampers are made of polyurethane flake foam. The damper has a dust-resistant skin on one side. The material is flame retardant according to EN ISO 11925-2:2002.

What sizes are available
The Inno dampers have a diametre of 80, 100, 125, 160, 200, 250 & 315 mm and a thickness of 50 mm. Inno dampers with a diameter of 250 and 315 mm are 80 mm thick. Minimum order 2 pieces per type.

Assembly Tips
By pressing one or more plugs out of the Inno dampers (or putting them back in), the best ratio between sound attenuation and airflow can be determined. Click here for the Product video on YouTube. The best result is achieved by placing 2 dampers in the air duct with a gap of +/- 10 cm with all plugs removed, one behind the other.
