Legend
Fire resistance class (EI60S, EI90S and EI120S), type of actuation (ZV, DV1 and DV1 -2), or accessories
(PRC-PKIC-DN and TVK-PKIC-DN) 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 PKI-C and air ow volume at different duct pressures.
