Measurement: LU-141116

Air performance measured as per:
ISO 5801, Installation category
A, without protection against
accidental contact.

Suction-side noise levels: 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.

For detailed information on the
measuring set-up, please contact
