Supply air side (with F7 filter)
Sound data is given at sound power level LwA in the capacity
diagrams and is corrected with the table below for the various
octave bands. Radiated noise produces Lw in the various octave
bands and total LwA. Radiated noise is estimated by finding the
noise level from the supply air table and deduct the total value
found in the correction factor table below.
