S-RA1
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 influence the airflow
parameter, therefore only one activation type is shown in the diagrams.
