Materials:
Iris Circular Duct Dampers are manufactured from hot dipped galvanised steel sheet and are equipped with an adjustment scale and measuring connections. The tamper proof control knob is adjusted with a spanner (the 80mm dia. has a lockable lever). Spigots are fitted as standard with rubber gaskets.

Installation:

For best results Iris Dampers should be installed in straight runs of ductwork. The damper can be connected by rivets or self-tapping screws. We recommend that all joints are sealed with sealant to ensure an airtight connection. Flexible ducting may be fixed to the damper using banding or clips.
