Easily-fitted silencer for circular ducts, fitted with a connection that complies with the spiral duct standard, the Duct Silencer effectively reduces noise in the duct. Two silencers can be used together in installations where noise reduction is a particularly strong requirement.
For the most effective noise reduction, the silencer should be fitted immediately behind the fan or bend. The silencer should be used together with an insulated fan where there is a requirement for noise reduction both in the duct and in the surroundings as a whole.
