Does this Iris Damper close completely for zero air flow?

Answer
No, the IR-Series Iris Dampers do not close completely, but flow can be determined based on the K factor and a differential pressure measurement. You would use the lever on the damper to select the K factor (related to how open the damper is). Please see the specification sheet for more details on air flow calculations.
