DescriptionDouble-layer inner duct wall. The inner duct wall is coveredwith a fibre glass insulation. The insulation is covered with adouble-layer outer duct.
The insulation reduces the heat gain or loss resulting from atemperature difference between the air flowing in the ductand the surrounding air.
The outer duct acts as a vapour barrier to prevent conden-sation to enter into the insulation. Condensation can occuron the outside of a duct carrying air at lower temperatures
than the surrounding air.
Advantages Small storage and transport volume.
Technical dataDuct materials:
inner wall.......................... Aluminium + aluminium (AL)insulation.......................... Glass wool 25 or 50 mmouter wall ......................... Aluminium + aluminium

Semiflexible double duct silencer SLFA 25
l in da b | f le xi bl e a nd s em if le xi bl e pr od uc ts
DescriptionSLFA 25 is a flexible silencer that can be adapted to anyinstallation situation. The bendability of the silencer allowsadaptation to very confined spaces and difficult wiring.Silencers are made from 2-layer, flexible aluminium tubes oftype SRF. The inner tube is micro-perforated and betweenthe inner and outer tubes is a 25 mm thick attenuation mate-rial layer of glass wool.The attenuation material reduces the noise passing throughthe silencer.The ends of the silencer are covered with aluminium gables.
The duct connections fits inside ducts.SLFA 25 comes in the dimensions 80-315 mm and 1000mm 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.
Technical dataDuct materials:
Inner wall: Aluminium + aluminium (AL)Insulation: Glass wool 25 mmOuter wall: Aluminium + aluminium
Minimum bending radius: 23dMaximum temperature: +200 CFire resistance: Not flammable in accordance

Semiflexible double duct silencer SLFA 50
l in da b | f l ex i bl e a nd s e mi f le x ib l e p ro d uc t s
DescriptionSLFA 50 is a flexible silencer that can be adapted to anyinstallation situation. The bendability of the silencer allowsadaptation to very confined spaces and difficult wiring.Silencers are made from 2-layer, flexible aluminium tubes oftype SRF. The inner tube is micro-perforated and betweenthe inner and outer tubes is a 50 mm thick attenuation mate-rial layer of glass wool.The attenuation material reduces the noise passing throughthe silencer.The ends of the silencer are covered with aluminium gables.
The duct connections fits inside ducts.SLFA 50 comes in the dimensions 80-315 mm and 1000mm 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.
Duct materials:Inner wall: Aluminium + aluminium (AL)Insulation: Glass wool 50 mmOuter wall: Aluminium + aluminium
Minimum bending radius: 23dMaximum temperature: +200 CFire resistance: Not flammable in accordance
with DIN 4102 class A1
