Description
SLFA 25 is a flexible silencer that can be adapted to any
installation situation. The bendability of the silencer allows
adaptation to very confined spaces and difficult wiring.
Silencers are made from 2-layer, flexible aluminum tubes of
type SRF. The inner tube is micro-perforated and between
the inner and outer tubes is a 25 mm thick attenuation material layer of glass wool.
The ends of the silencer are covered with aluminium gables.
The duct connections fits inside ducts.
SLFA 25 comes in the dimensions Ø80-315 mm and 1000
mm in length.
(Also available in lengths of 750, 1250, 1500 and 2000 mm).
The silencers can withstand temperatures up to 200 oC.
Advantages

• Small storage and transport volume.
