Dimensions and weights
The table lists the sound power values (SWL) in octave bands and totals; it also indicates the values of sound pressure level (SPL) at 1 m, 5 m and 10 m at supply, return and at the outside of the unit.All values refer to the operation of the ducted unit at FULL speed and at the nominal flow rate.
