ρ = 1.15 kg/m³ ± 2 %
Measurement: LU-58085-1
Air performance measured according to ISO
5801 installation category A. For detailed
information on the measurement setup,
contact ebm-papst. Intake sound level:
Sound power level according to ISO 13347 /
sound pressure level measured at 1 m
distance from fan axis. The values given are
valid under the specified measuring
conditions and may vary due to conditions of
installation. For deviations from the standard
configuration, the parameters have to be
checked on the installed unit.
