For detailed information on the measurement setup, contact ebm-papst. Intake sound level: Sound power level according to ISO / 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.
