Silencer

(DASD 150 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 a.

...in recirculation mode:

The silencer needs to be positioned

between the fan and the exhaust grille

b. The space needs to be checked in

some cases.

...air extraction with external fan:

To minimise noise from the fan in the

kitchen, the silencer should be

positioned in front of the external fan c

if possible, or if the ducting is long, then

in the ducting inside the rangehood

itself d.

In the case of an external fan placed

inside the house, fitting a silencer

behind the external fan e reduces the

noise of the fan outside the house.

In all modes of operation, the most

effective noise reductions are

achieved if two silencers are fitted in

the system.
