Silencer (DASD 150)

(optional extra)

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 motor outside the house, but

also sounds from outside (e.g. traffic

noise).

For this reason, the silencer must be

positioned as close as possible to the

ducting exit a.

. . . With air extraction with an

external motor:

To minimise fan noise in the kitchen, the

silencer should be positioned in front of

the motor b and, with longer exhaust

ducting, on the exhaust connection c

of the rangehood.

With an external motor installed within

the house, the use of a silencer behind

the external motor d enables a

reduction of fan noise by directing it

outside.

In all modes of operation, the most

effective noise reductions are

achieved if two silencers are fitted

one behind the other in the system.
