Not every fan has a quiet motor, and vibrations in a duct can also cause nuisance noise. Placing a flexible silencer on the fan or spiral duct is an easy way to limit noise from the ventilation system. Our non-woven silencer consists of a polypropylene inner duct, thermally and acoustically insulated with a layer of glass wool and finished with an aluminium laminate outer casing. Our silencers are available in a range of diameters and lengths.
