Sound Insulation
Inno Dampers, round silencers for round ventilation ducts 
Inno dampers sound-absorbing silencers insulate airborne noises before they become audible during the ventilation of apartments, houses and offices. Inno Dampers also reduce sound that gets transported by air through air ducts from one room or flat to another, such as voices, music and noise from installations. Inno dampers are easy to install without any tools, just remove some plugs to get more or less airflow.
How to install these foam air duct dampers
We recommend to use at least two Inno Dampers to reduce sufficient air borne noise coming from round air ducts. Remove the valve, clean the air duct, remove all plugs from the silencers, Inno Damper, and slide the dampers into the duct. Keep a distance of about 12 to 15 cm between each damper.
