General

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.

 

 

Product code


Inno-ERE is mainly made from a polyester fiber. This material fulfills the SBI-test, pr EN 13823 B-class (B,s1,d0).
Inno-ERE also contains small amounts of the flexible polyurethane foam. The material is flame resistant and conforms with FMVSS-302, the fabric flammability standard which is also used in e.g. automotive industry.

Inno-RP is mainly made from a flexible polyurethane foam.

Installation


Inno is incredibly easy to install, which makes it an ideal choice for 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.
