Inno is a damper for circular ducts. It is completely made from soft elastic plastic foam with good damping abilities. The damper has a number of oval openings equipped with releasable plugs. The pressure drop across the damper is adjusted by varying the number of open holes. Inno is usable with both supply and exhaust air valves.
Inno dampers are available from all good ventilation wholesalers in Europe. If you can’t find a wholesaler in your country, please contact us jeven(at)jeven.fi.
