The IRIS damper can be used in both exhaust and supply lines. It is equipped with lever for adjusting the hole diameter and two terminals for connection of flow control. The adjusting lever has two screws that block the desired throttle setting.
The IRIS damper is made of galvanized steel and has two rubber seals for tight fitting in the duct.

Dampers should be mounted in the duct, providing straight sections:
- 4 x diameter of the duct before the throttle
- 1 x diameter of the duct behind the throttle
