8/34 | F-C2
Diagrams
Accessory CBR-C2 and fire resistance class (EI60S, EI90S and EI120S) do not affect the pressure drop and A-weighted
total discharged sound power level.
The pressure drop and A-weighted total discharged sound power level depend on the nominal diameter of the F-C2
and air flow volume at different duct pressures.
