LWA as per ISO 13347, LPA
measured at 1m distance to
fan axis.
The values given are valid
under the measuring
conditions mentioned and
may vary accoring to the
actual installation situation.
With any deviation to the
standard set-up, the specific
values have to be checked
and reviewed once installed
or fitted.
