Damper and Silencer Inno for Circular Ducts, Jeven

Art. no.: 6699900

Inno is a damper for circular ducts. It consists entirely of soft elastic foam plastic with good sound reduction properties. The damper has a number of oval openings provided with extendable plugs.
The pressure drop across the damper is controlled by varying the number of open holes. The special material and hole design also provide low noise relief even with high pressure drops.
Inno is equipped with a measuring socket for quick adjustment.
