Silencer
(optional accessory)
To achieve even further reductions in
noise levels, a special silencer can be
fitted in the ducting system...
Connection for air extraction
...with air extraction:
The silencer not only reduces noise
from the fan, but also sounds from
outside (e.g. traffic noise).
For this reason the silencer must be
positioned as close as possible to
where the ducting leaves the building
.
...air extraction with external motor:
To minimise noise from the motor in the
kitchen, the silencer should be
positioned in front of the external motor
if possible, or if the ducting is long,
then in the ducting above the cooker
hood itself
.
In the case of an external motor placed
inside the house, fitting a silencer
behind the external motor
the noise of the motor outside the
house.
In all modes of operation, the most
effective noise reductions are
achieved if two silencers are fitted
one behind the other in the system.
