Inno

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.

FUNCTIONING PRINCIPLE

The pressure and air mass flow is easily adjusted by varying the number of open holes in the damper. The unique material and design of the damper results in low sound generation, even at large pressure drops. Inno is incredibly easy to install, which makes the damper ideal for use with existing installations.

The stable plastic foam has an open cellular structure and high density, which means extraordinary ability to absorb sound. Because of this the damper doubles as a simple silencer. The placement of several Innos one after another in a duct reduces noise, and sound problems such as overhearing between rooms can often be solved using Inno.

Inno is very easy to use with existing installations. Simply insert Inno into the duct opening from the room side. No tools are needed. The formable damper will seal tightly against the duct wall. Inno can be easily cleaned with a vacuum.

By placing several Innos after one another in a duct, the silencing is increased further. Inno can be easily cleaned with a vacuum during duct cleaning.
