Levels:
*As corrected for point of operation (location on fan curve)
**Unsilenced Inlet and Outlet power ratings are 3 dB lower than total fan power levels under the assumption that "half" of the sound power
can be attributed to each opening. Silenced power ratings include this 3 dB reduction as well as the silencer attenuation.
Estimated Sound Pressure Levels Expressed in dB (pressure levels reference 2x10 -7 microbar)
This fan is connected to both inlet and outlet ducting which routes most sound away from the designated sound
measurement location. The Housing Radiated Sound Power levels are the basis for sound pressure level
calculations.
The estimated sound pressure level outside the fan due to Housing Radiated Noise is 49.4 dBA at 10.0 feet.
