FDR-3G
Diagrams
The pressure drop and A-weighted total discharged sound power level depend on the nominal diameter of the damper
and air flow volume at different duct pressures. The type of activation does not influences the airflow parameter,
therefore only one activation type is shown in the diagrams.
